If I’m understanding this correctly this opens up the door to a serious type of rootkit.
It’s not a matter of attackers having access to the data. It’s that they have replaced your hardware with malicious hardware.
Additionally It can be trivial to gain administrative capacity on a personal computer. But in a regular case you can just reinstall the operating system. This would survive that.
On some level yes, but reading the article nothing persist between boots. This seems like a vulnerability that’s really only that serious A if you don’t apply AMDs patched micro code and B there’s another vulnerability on your system that lets this persist between operating system reinstall/in the BIOS.
Edit: seems I may be mistaken.

That’s not what this is about. It can’t even survive a reboot.
Ah, thanks for the clarification.
