AMD today announced, via a security blog post penned by their own Mark Papermaster, that they’re beginning deployment of mitigations and resources for AMD processors affected by the Spectre exploits. In the blog post, AMD reiterates how exploits based on version 1 of Spectre exploits (GPZ 1 – Google Project Zero Flaw 1) have already been covered by AMD’s partners. At the same time, AMD reiterates how their processors are invulnerable to Meltdown exploits (GPZ3), and explains how mitigations for GPZ2 (Spectre) will occur.
These mitigations require a combination of processor microcode updates from OEM and motherboard partners, as well as running the current and fully up-to-date version of Windows. For Linux users, AMD-recommended mitigations for GPZ Variant 2 were made available to Linux partners and have been released to distribution earlier this year.
