Requires kernel-level access. Also AMD is "releasing mitigations," so is it "unfixable?"

Requires kernel-level access

What does that mean to the rest of us?

It means it's what we in the trade call "a nothingburger". On Windows you need to explicitly install a malicious driver (which in turn requires to you to disable signature verification), on Linux you'd have to load a malicious kernel module (which requires pasting commands as root, and it would probably be proprietary since it has malware to hide and as every nvidia user knows, proprietary kernel modules break with kernel updates)
