AMD Patches Spectre Variant 2
AMD is on the ball about as much as any company can be when it comes to trying to patch hardware flaws in their processors. The good news is that they've patched the Spectre issue that cropped up with the second variant, but the bad news is that you'll have to wait for a BIOS update for your mainboard - or system board in your laptop in order to apply the patch. Hopefully things get figured out sooner rather than later.
AMD's update has been made available to its hardware partners, with patches designed for processors going back to CPUs built on 2011's "Bulldozer" architecture. While that's likely most in current operation, it's not clear exactly which processors have received the patches. It's also not clear when end users will see the fix, as you'll have to wait for the maker of your desktop or motherboard to release a new BIOS with the patch wrapped in.
