AMD has patched its processors to defend against Spectre

By Darren Allan

AMD has pushed out firmware patches to protect its processors against variant 2 of the Spectre vulnerability, in conjunction with updates for Windows 10 which are also designed to squash this particularly nasty bug.

As we’ve been told before, Spectre (and indeed Meltdown – although that only affects Intel chips) is a complex vulnerability which requires patches to firmware on the hardware front, and also for operating systems on the software side of the equation.

So, AMD has released microcode updates for its processors which, when combined with the aforementioned Windows updates, will defend users from Spectre variant 2.

The company stated: “These mitigations require a combination of processor microcode updates from our OEM and motherboard partners, as well as running the current and fully up-to-date version of Windows.”

Back to Bulldozer

AMD didn’t specify the exact CPU models which were covered by the fixes, but said that microcode updates were being released for all processors dating back to the first ‘Bulldozer’ products which went on sale in 2011.

Of course, the patches have been released to manufacturers, who will then have to put together BIOS updates which AMD chip owners can subsequently download. In other words, you’ll have to wait for the …read more
