I am curious what hardware vuln exists? Which manufacturer and model?

I'm assuming it's some sort of problem with the Intel MMU which allows either exposing someone else's PHYS mapped space (bad) or, possibly much worse, flipping a bit in an arbitrary person's mapped space.

The latter would allow a trivial privilege escalation attack that would give the attacker "root" on whoever he ran it against -- and the obvious target then is the hypervisor itself since that gives you instant access to the entire physical mapped address space of ALL of the clients.
