Yeah, and to exploit it you need ring0 access in the kernel.

In other words, this isn't an attack vector, it's an escalation path. It escalates past the kernel, which is terrible to be sure, but if a hacker manages to get that deep in the first place, your system is already fucked.

I have a pretty new AMD system I use for gaming. The vast majority of games run in a Windows VM in Proxmox with GPU passthrough with exception to Fortnite which runs directly on hardware on a different boot drive specifically because Easy Anticheat blocks VMs. That dedicated install becomes less and less attractive by the day.
