AMD processors will get a firmware update for the Spectre CPU exploit, but it's optional

AMD will release firmware updates for its processors to protect against the devastating Spectre CPU exploits that affect every modern computer, phone, and tablet. Unlike Intel’s flurry of CPU firmware updates, however, they aren’t being treated as critical must-install patches.

When Meltdown and Spectre were uncovered, AMD said that its CPUs aren’t vulnerable to Meltdown, the first Spectre flaw would be resolved via operating system and software updates, and “differences in AMD architecture mean there is a near zero risk of exploitation” of the Spectre second variant. Nevertheless, while AMD CTO Mark Papermaster says “we believe that AMD’s processor architectures make it difficult to exploit Variant 2,” AMD now plans to patch its CPUs against it.
