AMD’s advice is to upgrade to the ADM PSP driver 5.17.0.0 through Windows Update, or to download AMD Chipset Driver 3.08.17.735. Presumably, this solves the issue by properly zeroing out memory during allocation, as well as freeing up memory properly when its no longer needed.
Overall, a software fix is enough to solve the issue, and its a vulnerability that lacks some of the scare factor of bigger finds like Meltdown and Spectre from years past.
Sounds like they have their shit together.
One article about a patched vulnerability isn't special or indicative of anything on a wider scale.
