    Edit.
    New Ryzen Chipset Driver Patches Security Vulnerabilities

    AMD does not state which vulnerabilities were fixed

    Not the first time AMD won't bother talk about what's fixed or about their ongoing vulnerability and security flaws.

    AMD once again back in the (security vulnerability) spotlight.

    AMD Chipset Vulnerability Leaks Passwords, Patch Available tomshardware.com | Sept 17, 2021

    AMD originally issued the patch several weeks ago, but without disclosing which vulnerabilities were addressed. This new disclosure answers those questions.

    The security researcher first discovered the flaw with Ryzen 2000- and 3000-series platforms, but AMD initially listed only Ryzen 1000 and older chips in its advisory. The researcher noted the discrepancy in his report, and we followed up with AMD about the issue. AMD has since updated the page with a full list of impacted platforms that spans its entire modern consumer processor lineup as well as many older models (list below).

    AMD's processors have gained a reputation for being more secure than Intel's chips due to far fewer discovered vulnerabilities. However, as the smaller player with less overall x86 market share, it has long been opined that AMD's processors simply haven't been subject to as much poking and prodding from researchers. Now that AMD has taken a more significant portion of the market and continues to grow it is inevitable that researchers, and nefarious actors, will target the processors more frequently.

    • 2nd Gen AMD Ryzen Mobile Processor with Radeon Graphics
    • 2nd Gen AMD Ryzen Threadripper processor

    Microsoft want that you scrap your 3 years old computer for newer to enjoy Win 11. Of course they all want that you shuffle up more cash from you pockets for newer HW.

    Say goodbye to DX12 on 4th Gen Haswell CPUs as Intel defused it to fight off security bug neowin.com | Nov 5, 2021

    Intel says that some of its integrated GPUs contain a security vulnerability that may allow escalation of privilege. In a bid to mitigate the weakness, Intel decided to disable DirectX 12 API support on Haswell platforms, which naturally means that DirectX 12 games will no longer work on Haswell-based systems that use integrated GPUs. Those who need to run DirectX 12 applications based on the said GPU are advised to downgrade the driver to version 15.40.42.5063 or older.

    Yep, the fastest way to push you on new modern HW, just disable features or castrate the performance.

    Gosh, no more DX12 on the iGPU? All those low quality at 720p gaming moments will be lost...

    Yeah as long as Haswell laptops with dGPUs are still are able to run DX12 games, nothing is lost.

    Haswell iGPU is Gen 7.5 graphics released in 2013, nobody wants to play DX12 on these slow iGPUs. Depending on the exact SKU Haswell only gets 500-1000 points in Firestrike. Iris Xe G7 can go from 3500 to 6000 points depending on the memory and power setting. From the beginning of dx12 only Skylake and newer were really dx12 supported from Intel since Haswell isn't driver supported anymore.

    AMD Discloses 50 Security Holes Affecting EPYC CPUs, Radeon Drivers tomshardware.com | Today

    Someone call a plumber

    AMD published three security bulletins yesterday addressing the security vulnerabilities affecting its EPYC processors and the Radeon graphics driver for Windows 10. Although many are marked High severity, they are mitigated with a driver update and AGESA packages.

    The chipmaker exposed 22 potential vulnerabilities that affect three generations of EPYC processors: EPYC 7001 (Naples), EPYC 7002 (Rome) and EPYC 7003 (Milan). The exploits specifically target the AMD Platform Security Processor (PSP), AMD System Management Unit (SMU), AMD Secure Encrypted Virtualization (SEV) and other platform components.

    In response to the exploits, AMD distributed the the NaplesPI-SP3_1.0.0.G, RomePI-SP3_1.0.0.C and MilanPI-SP3_1.0.0.4 AGESA updates to its OEM partners. If you're running one of AMD's EPYC chips, you should contact your OEM for the update.


    Crucial BIOS update rolling out for Intel 11th Gen, 10th Gen, and more CPUs, fixes LPE bug neowin.com · Nov 11, 2021

    Intel has published an updated security advisory for a couple of new LPE bugs that were discovered. A lot of the newer CPUs, except Alder Lake, are vulnerable too. Firmware patches are rolling out....

    As far as recommendations, Intel has advised users to update the systems' BIOS to the firmware version that patches the issue. Hence, users should be on the lookout for when their OEMs or motherboard vendors release the patched firmware.
