AMD has released new microcode updates for mitigating variant 2 of the Spectre attack, and Microsoft has released an OS update with the mitigation to AMD users running Windows 10.

As you would possibly remember, AMD processors were found not to be susceptible to Meltdown attacks, but they were suffering from Spectre (both variants). Variant 1 necessitates application-level fixes, and variant 2 (CVE-2017-5715) requires changes at the OS level.

Microsoft fixes problem for Windows 10 users

The mitigation is named indirect branch prediction barrier (IBPB), making the processor guarantee that older indirect branches cannot influence predictions of indirect components within the future.

“As this restricts the processor from using all previous indirect branch information, it’s intended only to be employed by software when switching from one user context to a different user context that needs protection, or from one guest to a different guest,” AMD explained.

IBPB is that the AMD recommended setting for Windows mitigation, and IBPB combined with Retpoline software support is that the AMD recommended setting for Linux mitigation of the attack.

“‘Retpoline’ sequences are a software construct that permits indirect branches to be isolated from speculative execution. This might be applied to guard sensitive binaries (such as OS or hypervisor implementations) against branch target injection attacks against their indirect branches,” Google explained.

“The name ‘retooling may be a portmanteau of ‘return’ and ‘trampoline.’ it’s a trampoline construct constructed using return operations which also figuratively ensures that any associated speculative execution will ‘bounce’ endlessly.”

Still more to come

AMD has also explained that support for these mitigations for AMD processors in Windows Server 2016 is within the final stages of validation and testing. Therefore the updates are likely to be released soon.

Windows 10 users are advised to implement the KB4093112 update.

“In addition, microcode updates with our recommended mitigations addressing Variant 2 (Spectre) are released to our customers and ecosystem partners for AMD processors dating back to the primary ‘Bulldozer’ core products introduced in 2011,” Mark Papermaster, Senior vice chairman and Chief Technology Officer at AMD added.

“AMD customers are going to be ready to install the microcode by downloading BIOS updates provided by PC and server manufacturers and motherboard providers.”

Earlier this month, Intel announced that it had completed the discharge of microcode updates for all the microprocessors they launched within the last nine approximately years and required Meltdown and Spectre patches. the corporate also said that they’re going not to provide microcode updates to plug Spectre and Meltdown vulnerabilities during several older processors.

  1. Meltdown & Spectre Patches For AMD Processors – How Old???

My HP Pavilion dv6700z uses the AMD Turion ™ 64 X2 Mobile Technology TL-58 Dual Core Processor running Windows 7 Ultimate. I even have a separate HDD with Windows 10 and are testing multiple Win10 Builds as an Insider since October 2014 using this same dv6700z – it works great. This was a Vista PC originally, purchased from HP in December 2007. How far back in time will Microsoft patch AMD Processors, and if we are near the time cutoff, how can we determine if we cut? In Device Manager Details, the Processor Install Date is 1/27/2010, possibly because I replaced the Motherboard and AMD CPU with a more modern MB and Processor. AMD Hardware ID is ACPI\AuthenticAMD_-_AMD64_Family_15_Model_104.

3.Windows 10 just updated on an Intel CPU with an AMD processor, and it won’t boot now (Meltdown / Spectre Patches)

My computer just updated automatically, and now it won’t begin. It has been up so far, and that I assume this is often the Meltdown / Spectre patches…

The system has an Intel CPU (don’t ask what model because I can not tell without removing the cooler)

The GPU is AMD… I noticed that on searching on Google, the verge has a piece of writing that mentions this issue with these patches affects some systems with Intel CPUs and AMD GPU’s…
