Spectre Patches for AMD Ryzen, EPYC Systems To Begin This Week
A new solar day and a new hardware vendor has announced the rollout of Spectre patches to ready the vulnerabilities. While Intel and Nvidia are already patching their firmware and driver software respectively, it is now the turn of AMD to announce updates for its CPUs to mitigate the threats posed by the recently-revealed exploits.
According to AMD, two Spectre variants, GPZ 1 (Premises Cheque Bypass) and GPZ 2 (Co-operative Target Injection), are applicative to AMD processors, although, they are not affected in whatever style by Meltdown (GPZ variant 3 / Rogue Data Enshroud Load) because of the visitor'southward utilise of "privilege level protections inside paging architecture".
The first adventure can exist mitigated just past patching the operating organization, which is why AMD says it is working with OS vendors to address this upshot. GPZ variant two, however, will require some microcode updates from AMD in addition to Bone patches. The company says it volition make the patches bachelor for Ryzen and EPYC chips this week itself, with the previous generation products receiving the optional patches "over the coming weeks".
For now, the incoming updates are patches meant for operating systems and not the visitor's CPU firmware. AMD says that the patches for Ryzen and EPYC fries will go along to roll out fifty-fifty as it tries to sort out the issues faced by older AMD processors (AMD Opteron, Athlon and AMD Turion X2 Ultra families) later on installing some of the fixes that were rolled out as office of the last Patch Tuesday.
Microsoft is expected to starting time rolling out the fixed software for older AMD CPU lineups "by next week". Linux vendors are also starting to roll out OS patches for its CPUs across the lath, co-ordinate to the company.
In instance y'all're wondering when AMD will start patching its GPU cards, the company has skillful news for you. "AMD Radeon GPU architectures do not use speculative execution and thus are non susceptible to these threats", says Mark Papermaster, Senior Vice President and Chief Technology Officer of the company.
