Spectre Patches for AMD Ryzen, EPYC Systems To Begin This Week

A new day and a new hardware vendor has announced the rollout of Spectre patches to fix 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 (Bounds Check Bypass) and GPZ 2 (Branch Target Injection), are applicable to AMD processors, although, they are not affected in any way by Meltdown (GPZ variant 3 / Rogue Data Cache Load) because of the company’s use of “privilege level protections within paging architecture”.
