So if I get this correctly, as long as the Host OS is 64bit we're fine, since VME isn't supported on that anyways? I'm thinking 32bit hosts running VMs of any sort should be an increasingly rare case, but nevertheless it's going to be interesting to see if and when AMD releases a fixed version.



It can affect 32-bit guest OSes running on 64-bit hosts, and that is how they discovered the bug.


A 64-bit host, running a 32-bit guest, itself running a 16-bit app. This scenario can run into the VME bug.


Any exploitation scenarios here?

Could you package a trimmed down version of that stack up and cause a reliable crash on Ryzens operating on a more typical platform?

Maybe it becomes a bit of a rube goldberg malware at that point...


The first part of that is optional, and the last part of that is also optional.


Or a 64bit host running a WinXP guest.
