The Raspberry Pi 4 has hit a major graphics milestone, adding support for a more modern Vulkan 3D APIa. Ars Technica reports: Raspberry Pi CEO Eben Upton announced the Pi 4's Vulkan 1.2 conformance on Monday. Support isn't available yet in downloadable Pi-friendly operating systems but should be coming soon. For most people using their Pi as a server, a DIY controller, or a light desktop, Vulkan 1.2 conformance won't be noticeable. Desktop graphics on the standard Raspberry Pi OS are powered by OpenGL, the older graphics API that Vulkan is meant to replace. There is one group that benefits, says Upton: games and other 3D Android applications. Android uses Vulkan as its low-overhead graphics API.

As with most Raspberry Pi advancements, there could be unforeseen opportunities unleashed by this seemingly tiny change. Vulkan 1.2 support gives developers the same 3D-graphics interface (if not anywhere near the same power) as 2019 NVIDIA graphics cards, 2020 Intel chips with integrated graphics, and dozens of other devices. With a Vulkan 1.0 driver installed, developer Iago Toral was able in 2020 to get the original Quake trilogy mostly running on a Pi 4, with not-too-shabby frame rates.

As the US Congress passed an historic $52 billion federal program to boost domestic chipmaking capabilities, it included one significant caveat: Companies that receive the funding have to promise not to increase their production of advanced chips in China. From a report: It's a condition that will certainly add to escalating tensions between Washington and Beijing. The curbs will hit companies like Intel Corp. and Taiwan Semiconductor Manufacturing Co., leading chipmakers that have tried to build their businesses in China. TSMC won't be able to substantially upgrade or expand its existing facilities, effectively losing some growth opportunities in the world's biggest semiconductor market.

Specifically, the Chips and Science Act bars companies that get federal funding from materially expanding production of chips more advanced than 28-nanometers in China -- or a country of concern like Russia -- for 10 years. While 28-nanometer chips are several generations behind the most cutting-edge semiconductors available now, they are still used in a wide range of products including cars and smartphones. The ban covers both logic and memory chips.

According to a new report from ETNews, Intel is planning to install its next-generation Wi-Fi 7 (802.11be) technology in devices by 2024 as Apple transitions its devices to Wi-Fi 6E. MacRumors reports: Wi-Fi 7 is the successor to Wi-Fi 6E (802.11ax), bringing two times faster data processing speeds of 5.8 Gbps and more stable 6 GHz bandwidth stability, as well as support for up to 36 Gbps when working with data. Intel plans to expand its Wi-Fi 7 development efforts ahead of its introduction to the market in 2024 and intends to apply its technology predominantly in laptops before expanding to other devices. "We are currently developing Intel's Wi-Fi '802.11be' in order to obtain the 'Wi-Fi Alliance' certification, and it will be installed in PC products such as laptops by 2024. We expect it to appear in major markets in 2025," Eric McLaughlin, vice president of Intel's wireless solutions division, said at a recent press conference in Asia.

Meanwhile, Apple is on the cusp of transitioning its devices to Wi-Fi 6E. While it was heavily rumored to debut with the iPhone 13 lineup last year, Apple has yet to release any devices with support for Wi-Fi 6E. That is expected to change this year starting with the iPhone 14. Apple's long-rumored mixed-reality headset is also expected to feature Wi-Fi 6E. Apple analyst Ming-Chi Kuo said that head-mounted display devices in 2022, 2023, and 2024 will offer Wi-Fi 6/6E, Wi-Fi 6E/7, and Wi-Fi 7, respectively, but it is unclear if this information was related to Apple's product roadmap specifically. "Wi-Fi 6E offers the features and capabilities of Wi-Fi 6, including higher performance, lower latency, and faster data rates, extended into the 6 GHz band for processing speeds of 2.4 Gbps," notes MacRumors. "The additional spectrum provides more airspace beyond existing 2.4GHz and 5GHz Wi-Fi, resulting in increased bandwidth and less interference."

Other tech giants like Qualcomm, Broadcom, and MediaTek are also planning to release Wi-Fi 7-based products in the next few years.

An anonymous reader quotes a report from The Register: The US Commerce Department says it will strictly control use of subsidies under the recently passed CHIPS and Science Act, which promises to unlock billions of dollars in funding for domestic chip manufacturing. The eagerly anticipated spending bill paves the way for $280 billion in funding for science and technology, roughly $52 billion of which is earmarked for boosting US semiconductor production. Its passing was greeted by companies such as Intel and Micron, the latter of which promised to ramp up stateside memory production over the next few years in exchange for some of that cash.

However, the Commerce Department has given chipmakers notice that it will not be allowing a free-for-all, and will not let them use government funding for "stock buybacks or to pad their bottom line," it said in a published statement. Instead, subsidies awarded will be "no larger than is necessary to ensure a project happens here in the United States," the Commerce Department said, adding that it wanted to avoid a situation where states and municipalities became embroiled in a subsidy competition in the race to attract chipmakers to build there. The Department also warned that it will not hesitate to clawback funds or pursue other remedies from semiconductor companies that are found to have misused taxpayer dollars. Funding will come with conditions attached: chipmakers that receive a CHIPS subsidy will be prohibited from engaging in "significant transactions in China or other countries of concern" involving any leading-edge semiconductor manufacturing capacity for a period of ten years.

New submitter mrex writes: More than 60 major American companies that employ tens of thousands of U.S. workers are asking the Supreme Court to uphold the use of race as a factor in college admissions, calling affirmative action critical to building diverse workforces and, in turn, growing profits. The businesses -- some of the most high-profile and successful in the U.S. economy -- outlined their position in legal briefs filed Monday ahead of oral arguments this fall in a pair of cases expected to determine the future of the race-based policy. The companies told the court they rely on universities to cultivate racially diverse student bodies which in turn yield pools of diverse, highly educated job candidates that can meet their business and customer needs. "The government's interest in promoting student-body diversity on university campuses remains compelling from a business perspective," the companies wrote in an amicus, or friend-of-the-court, brief. "The interest in promoting student-body diversity at America's universities has, if anything, grown in importance." Among the signatories are American Express, United and American Airlines, Apple, Intel, Bayer, General Electric, Kraft Heinz, Microsoft, Verizon, Procter & Gamble and Starbucks. Citing data and research on a rapidly diversifying America, the companies said race-based diversity initiatives are about more than what many call a moral imperative and critical to their bottom lines. "Prohibiting universities nationwide from considering race among other factors in composing student bodies would undermine businesses' efforts to build diverse workforces," they said.

An anonymous reader quotes a report from Gizmodo: Intel could really use a few bucks from the recently passed (by Congress, at least) $280 billion CHIPS and Science ACT. The U.S. chipmaker shocked investors on Thursday, revealing it lost nearly $500 million in Q2, its first quarterly loss in years. The company cited weakened demand for PC components and downturns in the broader economy as the main culprits for the declines. Overall, Intel's revenues were down 22% year over year. Those results have forced Intel to lower its expected yearly revenues down from $68 billion to $65 billion. Yikes.

Intel CEO Pat Gelsinger said the results were "disappointing." "This quarter's results were below the standards we have set for the company and our shareholders," Gelsinger said. "We must and will do better. The sudden and rapid decline in economic activity was the largest driver, but the shortfall also reflects our own execution issues." He continued. "We are being responsive to changing business conditions, working closely with our customers while remaining laser-focused on our strategy and long-term opportunities. We are embracing this challenging environment to accelerate our transformation." In his prepared statements, Chief Financial Officer David Zinsner elaborated on the declines, saying a worse than expected covid-19 related downturn was partly responsible for declining consumer demand. On the economic side, Zinsner said a combination of rising inflation, higher interest rates, and downstream effects from the war in Ukraine hit the company particularly hard. "Due to the difficult macroeconomic environment together with our own execution challenges, our results for the quarter were well below expectations and necessitate a significant revision to our full-year financial guidance," Zinsner said.

Now, Intel says it's planning to pass on some of that inflationary pricing to consumers. In statements first spotted by PC World, Zinsner reportedly confirmed the company's getting ready to hike prices for components, so you might want to buy any new Intel chips before the fourth quarter. While Zinsner didn't say how much prices will rise by, previous reports claim the company's considering increases of up to 20% for certain processors. "You know we can absorb a lot of inflationary impacts that others can't," Zinsner said, according to PC World. "But at this point now that some of the price increases, inflationary increases, have turned out to be more permanent, where there's a certain amount that we do need to pass on to the customers." "As we look beyond the near term, the semiconductor industry continues to be at the beginning of a new structural growth phase driven by four superpowers: ubiquitous compute, pervasive connectivity, cloud-to-edge infrastructure and AI," added Gelsinger. "What remains very clear, even during this period of uncertainty, is the growing importance of silicon to the global economy and to each of our daily lives."

An anonymous reader quotes a report from Ars Technica: Intel is slowly moving into the dedicated graphics market, and its graphics driver releases are looking a lot more like Nvidia's and AMD's than they used to. For its dedicated Arc GPUs and the architecturally similar integrated GPUs that ship with 11th- and 12th-generation Intel CPUs, the company promises monthly driver releases, along with "Day 0" drivers with specific fixes and performance enhancements for just-released games. At the same time, Intel's GPU driver updates are beginning to de-emphasize what used to be the company's bread and butter: low-end integrated GPUs. The company announced yesterday that it would be moving most of its integrated GPUs to a "legacy support model," which will provide quarterly updates to fix security issues and "critical" bugs but won't include the game-specific fixes that newer GPUs are getting.

The change affects a wide swath of GPUs, which are not all ancient history. Among others, the change affects all integrated GPUs in the following processor generations, from low-end unnumbered "HD/UHD graphics" to the faster Intel Iris-branded versions: 6th-generation Core (introduced 2015, codenamed Skylake), 7th-generation Core (introduced 2016, codenamed Kaby Lake), 8th-generation Core (introduced 2017-2018, codenamed Kaby Lake-R, Whiskey Lake, and Coffee Lake), 9th-generation Core (introduced 2018, codenamed Coffee Lake), 10th-generation Core (introduced 2019-2020, codenamed Comet Lake and Ice Lake), and various N4000, N5000, and N6000-series Celeron and Pentium CPUs (introduced 2017-2021, codenamed Gemini Lake, Elkhart Lake, and Jasper Lake).

Intel is still offering a single 1.1GB driver package that supports everything from its newest Iris Xe GPUs to Skylake-era integrated graphics. However, the install package now contains one driver for newer GPUs that are still getting new features and a second driver for older GPUs on the legacy support model. The company uses a similar approach for driver updates for its Wi-Fi adapters, including multiple driver versions in the same download package to support multiple generations of hardware. "The upshot is that these GPUs' drivers are about as fast and well-optimized as they're going to get, and the hardware isn't powerful enough to play many of the newer games that Intel provides fixes for in new GPU drivers anyway," writes Ars Technica's Andrew Cunningham. "Practically speaking, losing out on a consistent stream of new gaming-centric driver updates is unlikely to impact the users of these GPUs much, especially since Intel will continue to fix problems as they occur."

In the M2 MacBook Air, Apple has replaced an Intel-made component responsible for controlling the USB and Thunderbolt ports with a custom-made controller, meaning the last remnants of Intel are now fully out of the latest Mac. MacRumors reports: Earlier this month, the repair website iFixit shared a teardown of the new "MacBook Air," revealing a look inside the completely redesigned machine. One subtle detail that went largely unnoticed was that unlike previous Macs, the latest "MacBook Air" introduces custom-made controllers for the USB and Thunderbolt ports. iFixit mentioned it in their report, noting they located a "seemingly Apple-made Thunderbolt 3 driver, instead of the Intel chips we're familiar with." The new component was shared on Twitter earlier today, where it received more attention. Few details are known about the controllers, including whether they're custom-made by Apple or a third party.

Intel Linux GPU driver developers have released an update that results in a massive 100X boost in ray tracing performance. This is something to be celebrated, of course. However, on the flip side, the driver was 100X slower than it should have been because of a memory allocation oversight. Tom's Hardware reports: Linux-centric news site Phoronix reports that a fix merged into the open-source Intel Mesa Vulkan driver was implemented by Intel Linux graphics driver engineering stalwart Lionel Landwerlin on Thursday. The developer wryly commented that the merge request, which already landed in Mesa 22.2, would deliver "Like a 100x (not joking) improvement." Intel has been working on Vulkan raytracing support since late 2020, but this fix is better late than never.

Usually, the Vulkan driver would ensure temporary memory used for Vulkan raytracing work would be in local memory, i.e., the very fast graphics memory onboard the discrete GPU. A line of code was missing, so this memory allocation housekeeping task wasn't set. Thus, the Vulkan driver would shift ray tracing data to slower offboard system memory and back. Think of the continued convoluted transfers to this slower memory taking place, slowing down the raytracing performance significantly. It turns out, as per our headline, that setting a flag for "ANV_BO_ALLOC_LOCAL_MEM" ensured that the VRAM would be used instead, and a 100X performance boost was the result. "Mesa 22.2, which includes the new code, is due to be branched in the coming days and will be included in a bundle of other driver refinements, which should reach end-users by the end of August," adds the report.

U.S. chipmaker Intel said on Monday it will produce chips for Taiwan's MediaTek, one of the world's largest chip design firms. From a report: The manufacturing arrangement is one of the most significant deals Intel has announced since it launched its so-called foundry business early last year.

The New York Times' product-recommendation service "Wirecutter" has sparked widening criticism about how laptops are reviewed. The technology/Apple blog Daring Fireball first complained that they "institutionally fetishize price over quality". That makes it all the more baffling that their recommended "Best Laptop" — not best Windows laptop, but best laptop, full stop — is a Dell XPS 13 that costs $1,340 but is slower and gets worse battery life (and has a lower-resolution display) than their "best Mac laptop", the $1,000 M1 MacBook Air.
Technically Dell's product won in a category titled "For most people: The best ultrabook" (and Wikipedia points out that ultrabook is, after all, "a marketing term, originated and trademarked by Intel.") But this leads blogger Jack Wellborn to an even larger question: why exactly do reviewers refuse to do a comparison between Wintel laptops and Apple's MacBooks? Is it that reviewers don't think they could fairly compare x86 and ARM laptops? It seems easy enough to me. Are they afraid that constantly showing MacBooks outperforming Wintel laptops will give the impression that they are in the bag for Apple? I don't see why. Facts are facts, and a lot of people need or want to buy a Windows laptop regardless. I can't help but wonder if, in the minds of many reviewers, MacBooks were PCs so long as they used Intel, and therefore they stopped being PCs once Apple switched to using their own silicon.
Saturday Daring Fireball responded with their own assessment. "Reviewers at ostensibly neutral publications are afraid that reiterating the plain truth about x86 vs. Apple silicon — that Apple silicon wins handily in both performance and efficiency — is not going to be popular with a large segment of their audience. Apple silicon is a profoundly inconvenient truth for many computer enthusiasts who do not like Macs, so they've gone into denial..."

Both bloggers cite as an example this review of Microsoft's Surface Laptop Go 2, which does begin by criticizing the device's old processor, its un-backlit keyboard, its small selection of ports, and its low-resolution touchscreen. But it ultimately concludes "Microsoft gets most of the important things right here, and there's no laptop in this price range that doesn't come with some kind of trade-off...." A crime of omission — or is the key phrase "in this price range"? (Which gets back to Daring Fireball's original complaint about "fetishizing price over quality.") Are Apple's new Silicon-powered laptops sometimes being left out of comparisons because they're more expensive?

In an update, Wellborn acknowledges that this alleged refusal-to-compare apparently actually precedes Apple's launch of its M1 chip. But he argues that now it's more important than ever to begin making those comparisons: It's a choice between a hot and noisy and/or slow PC laptop running Windows and a cool, silent, and fast MacBook. Most buyers don't know that choice now exists, and it's the reviewer's job to educate them. Excluding MacBooks from consideration does those buyers a considerable disservice.

The Dell XPS 13 Plus Developer Edition with Ubuntu 22.04 Long Term Support (LTS) will arrive on August 23rd. "This means, of course, Canonical and Dell officially have been certified for Ubuntu 22.04 LTS," writes ZDNet's Steven Vaughan-Nichols. "So if you already have a current XPS 13 Plus, you can install Ubuntu 22.04 and automatically receive the same hardware-optimized experience that will ship with the new Developer Edition." From the report: What this certification means is that all of XPS's components have been tested to deliver the best possible experience out of the box. Ubuntu-certified devices are based on Long Term Support (LTS) releases and therefore receive updates for up to 10 years. So if you actually still have an XPS 13 that came with Ubuntu back in the day, it's still supported today. [...] Dell and Canonical have been at this for years. Today's Dell's Developer Editions are the official continuation of Project Sputnik. This initiative began 10 years ago to create high-end Dell systems with Ubuntu preinstalled. These were, and are, designed with programmer input and built for developers.

As Jaewook Woo, Dell's product manager, Linux, explained: "XPS is an innovation portal for Dell -- from its application of cutting-edge technology to experimentation of new user interfaces and experiential design. By bringing the enhanced performance and power management features of Ubuntu 22.04 LTS to our most advanced premium laptop, Dell and Canonical reinforce our joint commitment to continue delivering the best computing experience for developers using Ubuntu."

The forthcoming Dell XPS Plus Developer Edition's specifications are impressive. The base configuration is powered by a 12th-generation Intel i5 1240P processor that runs up to 4.4GHz. For graphics, it uses Intel Iris Xe Graphics. This backs up the 13.4-inch 1920x1200 60Hz display. For storage, it uses a 512GB SSD. The list price is $1,389.

An anonymous reader quotes a report from Ars Technica: Unlike Intel Macs, Apple silicon Macs were designed to run only Apple's software. But the developers on the Asahi Linux team have been working to change that, painstakingly reverse-engineering support for Apple's processors and other Mac hardware and releasing it as a work-in-progress distro that can actually boot up and run on bare metal, no virtualization required. The Asahi Linux team put out a new release today with plenty of additions and improvements. Most notably, the distro now supports the M1 Ultra and the Mac Studio and has added preliminary support for the M2 MacBook Pro (which has been tested firsthand by the team) and the M2 MacBook Air (which hasn't been tested but ought to work). Preliminary Bluetooth support for all Apple silicon Macs has also been added, though the team notes that it works poorly when connected to a 2.4GHz Wi-Fi network because "Wi-Fi/Bluetooth coexistence isn't properly configured yet."

There are still many other things that aren't working properly, including the USB-A ports on the Studio, faster-than-USB-2.0 speeds from any Type-C/Thunderbolt ports, and GPU acceleration, but progress is being made on all of those fronts. GPU work in particular is coming along, with a "prototype driver" that is "good enough to run real graphics applications and benchmarks" already up and running, though it's not included in this release. The Asahi team has said in the past that it expects support for new chips to be relatively easy to add to Asahi since Apple's chip designers frequently reuse things and don't make extensive hardware changes unless there's a good reason for it. Adding basic support for the M2 to Asahi happened over the course of a single 12-hour development session, and just "a few days" of additional effort were needed to get the rest of the hardware working as well as it does with M1-based Macs.

Several U.S. semiconductor firms are deliberating whether to oppose a package of chip industry subsidies if the final language of the legislation awaiting a vote in the Senate disproportionately benefits manufacturers like Intel, sources familiar with the matter told Reuters. From the report: Senate Majority Leader Chuck Schumer has told lawmakers that a vote could come as early as Tuesday on a slimmed-down set of bills to bolster the U.S. computer chip industry, after Democratic lawmakers cleaved them from a larger, more contentious bill. The bills are aimed at making the U.S. more competitive against a rising China, whose chip industry has grown rapidly over the last five years to account for almost 10% of global sales. The measures include $52 billion in subsidies and an investment tax credit to boost U.S. manufacturing. The bills have bipartisan support, though Republicans may vote against the chip measures unless Democrats give up plans to try to push through unrelated spending bills that Republicans oppose. But a rift is emerging within the chip industry itself, with some players concerned the final language of the legislation could provide disproportionate support to manufacturers like Intel while doing little to support other chip makers like Advanced Micro Devices, Qualcomm and Nvidia.

"The lock screen is about to change," writes CNET — both for iOS and Android devices. Apple's iOS 16 update, which launched in public beta on Monday, will bring more customization options and new widgets to the iPhone's lock screen when it arrives this fall. You'll be able to see more information quickly and apply stylistic effects to lock screen photos similar to the iPhone's Portrait Mode photography feature.... Like the Apple Watch, the new lock screen should make it easier to see crucial pieces of information without having to dig into apps or even unlock your phone.
And for Android phones: Glance, a Google-backed subsidiary of mobile ad tech company InMobi, also reiterated its plans to bring its lock screen platform to the U.S. [though the company also says there's "no definitive timeline."] And Google is reportedly planning to incorporate more bits of information into its own lock screen widget for Pixel phones.... Glance's lock screen will appear in the form of what it calls "spaces," which are essentially curated lock screens designed to fit specific themes. A fitness-oriented lock screen, for example, would show statistics such as calories burned and exercise goals alongside a music player. A news "space" would show headlines and the weather, while a music version could surface live concerts....

The TechCrunch report about Glance's US arrival sparked concerns that advertisements would be coming to the lock screen, too. Glance's business page shows examples of advertisers that have used its platform to reach potential customers on the very first screen they see when picking up their phone. Intel, Zomato and Garnier are among the listed case studies. But Rohan Choudhary, vice president and general manager of the Glance feed, told CNET the US version would be ad-free. "We are very clear that in the US, we will not have ads on the lock screen at all," he said....

The company says it plans to monetize its service through news subscriptions and commerce links from shopping platforms that are surfaced through Glance.
Glance's motto? "Transforming lock screens into smart surfaces."

A senior systems administrator at the Free Software Foundation points out that they're running free software in two data centers and over a hundred virtual machine — each and every one with "a freedom-respecting BIOS."

But the "how" is surprisingly intricate: [E]arlier this week, we replaced "Columbia", the last of any FSF-run machines running a nonfree BIOS....

At FSF, our current standard is ASUS KGPE-D16 motherboards with AMD CPUs 6200 series CPUs released in 2012. For the BIOS, we install Libreboot, the easy-to-install, 100% free software replacement for proprietary BIOS/boot programs, or a version of Coreboot that is carefully built to avoid including any nonfree blobs. They are fast enough for our needs, and we expect this to be the case for many more years to come. They are also very affordable systems. We are also working toward supporting Raptor Computer Systems' newer and more powerful Talos II, as well as Blackbird motherboards that use IBM POWER9 CPUs. The POWER9 CPU architecture is called "PowerPC 64-bit little endian," abbreviated "ppc64el...." The Raptor motherboards come with entirely free firmware — and even have free hardware designs!

However, this type of migration has its challenges. For example, the first thing we needed to address before using these motherboards is that the main operating system we use, Trisquel GNU/Linux, didn't previously run on pp64el. So, earlier this year, we set up a Raptor POWER9 computer running Debian (without using any nonfree parts of Debian repositories) and loaned it to the maintainers of Trisquel for as long as needed. And now, we are proud to say that the upcoming Trisquel 11 release will support POWER9...!

Before I decommissioned Columbia, I ran a dmidecode, which told me that the BIOS program fit within a single megabyte of space. Often, very simplistic firmware becomes more complicated in later models, and that also usually means it has a growing significance for a user's software freedom. Some newer nonfree BIOSes have grown into operating systems in their own right, sometimes with large programs such as a full Web browser.

There is no fully-free BIOS available for x86 Intel and AMD CPUs released after about 2013. The key blocking factor is that those CPUs require certain firmware in the BIOS, like Intel Management Engine. Those CPUs will also refuse to run firmware that hasn't been cryptographically signed by private keys controlled by AMD and Intel, and AMD and Intel will only sign their own nonfree firmware. At the FSF, we refuse to run that nonfree firmware, and we applaud the many people who also avoid it. For those people who do run those Intel or AMD systems, running Coreboot or Osboot is still a step up the Freedom Ladder for the software freedom of your BIOS.

The road to freedom is a long road. We hope our dedication to achieve milestones like these can inspire the free software movement.

Intel has informed customers it will raise prices on a majority of its microprocessors and peripheral chip products later this year, citing rising costs, Nikkei Asia reported Thursday. From the report: The biggest U.S. chipmaker plans to raise prices this autumn on flagship products such as central processing units for servers and computers, where it dominates the market, as well as on a wide range of other items, including chips for Wi-Fi and other connectivity, according to three industry executives with direct knowledge. Intel says the price hikes are required because of the surging costs for production and materials, the executives said. The percentage increases have not been finalized, and could be different for different types of chips, but are likely to range from a minimal single-digit increase to more than 10% and 20% in some cases, one of the people said. Intel's move comes amid an inflation surge in the U.S. and around the world. The U.S. reported consumer prices rose 9.1% in June, a 40-year record.

Law students getting ready to take the Bar exam digitally may run into a serious issue: one of the nation's most frequently-used test-taking software packages, Examplify, is incompatible with Intel's latest generation of processors. From a report: In a notice to users, ExamSoft, the company that owns Examplify, writes that 12th Gen Intel processors aren't compatible with its software. "New Windows devices containing the Intel 12th generation chipset are triggering Examplify's automatic virtual machine check," Examplify's notice reads. "These are NOT currently supported. Therefore, they cannot be used for the upcoming July 2022 bar exam." One user drew attention to the issue in a post on Twitter, and included a screencap of what appears to be a notice given to Bar applicants.

Lenovo has released a security advisory to inform customers that more than 70 of its laptops are affected by a UEFI/BIOS vulnerability that can lead to arbitrary code execution. SecurityWeek reports: Researchers at cybersecurity firm ESET discovered a total of three buffer overflow vulnerabilities that can allow an attacker with local privileges to affected Lenovo devices to execute arbitrary code. However, Lenovo says only one of the vulnerabilities (CVE-2022-1892) impacts all devices, while the other two impact only a handful of laptops. "The vulnerabilities can be exploited to achieve arbitrary code execution in the early phases of the platform boot, possibly allowing the attackers to hijack the OS execution flow and disable some important security features," ESET explained. "These vulnerabilities were caused by insufficient validation of DataSize parameter passed to the UEFI Runtime Services function GetVariable. An attacker could create a specially crafted NVRAM variable, causing buffer overflow of the Data buffer in the second GetVariable call," it added.

Lenovo has also informed customers about Retbleed, a new speculative execution attack impacting devices with Intel and AMD processors. The company has also issued an advisory for a couple of vulnerabilities affecting many products that use the XClarity Controller server management engine. These flaws can allow authenticated users to cause a DoS condition or make unauthorized connections to internal services.

Some microprocessors from Intel and AMD are vulnerable to a newly discovered speculative execution attack that can covertly leak password data and other sensitive material, sending both chipmakers scrambling once again to contain what is proving to be a stubbornly persistent vulnerability. Ars Technica reports: Researchers from ETH Zurich have named their attack Retbleed because it exploits a software defense known as retpoline, which was introduced in 2018 to mitigate the harmful effects of speculative execution attacks. Speculative execution attacks, also known as Spectre, exploit the fact that when modern CPUs encounter a direct or indirect instruction branch, they predict the address for the next instruction they're about to receive and automatically execute it before the prediction is confirmed. Spectre works by tricking the CPU into executing an instruction that accesses sensitive data in memory that would normally be off-limits to a low-privileged application. Retbleed then extracts the data after the operation is canceled. [...] The ETH Zurich researchers have conclusively shown that retpoline is insufficient for preventing speculative execution attacks. Their Retbleed proof-of-concept works against Intel CPUs with the Kaby Lake and Coffee Lake microarchitectures and AMD Zen 1, Zen 1+, and Zen 2 microarchitectures.

In response to the research, both Intel and AMD advised customers to adopt new mitigations that the researchers said will add as much as 28 percent more overhead to operations. [...] Both Intel and AMD have responded with advisories. Intel has confirmed that the vulnerability exists on Skylake-generation processors that don't have a protection known as enhanced Indirect Branch Restricted Speculation (eIBRS) in place. "Intel has worked with the Linux community and VMM vendors to provide customers with software mitigation guidance which should be available on or around today's public disclosure date," Intel wrote in a blog post. "Note that Windows systems are not affected given that these systems use Indirect Branch Restricted Speculation (IBRS) by default which is also the mitigation being made available to Linux users. Intel is not aware of this issue being exploited outside of a controlled lab environment." AMD, meanwhile, has also published guidance. "As part of its ongoing work to identify and respond to new potential security vulnerabilities, AMD is recommending software suppliers consider taking additional steps to help guard against Spectre-like attacks," a spokesman wrote in an email. The company has also published a whitepaper.

[Research Kaveh Razavi added:] "Retbleed is more than just a retpoline bypass on Intel, specially on AMD machines. AMD is in fact going to release a white paper introducing Branch Type Confusion based on Retbleed. Essentially, Retbleed is making AMD CPUs confuse return instructions with indirect branches. This makes exploitation of returns very trivial on AMD CPUs." The mitigations will come at a cost that the researchers measured to be between 12 percent and 28 percent more computational overhead. Organizations that rely on affected CPUs should carefully read the publications from the researchers, Intel, and AMD and be sure to follow the mitigation guidance.
