I doubt that this can be used for VM escape because it requires access to the physical LAPIC and afaik hypervisors wouldn't allow VMs to touch this. It also doesn't work from userspace so pretty much all you can do with it is hacking SMM from a kernel running on the bare metal. Maybe useful for rootkits, but truth be told 3LAs seem to have no problem making non-SMM malware undetectable by commercial AVs. See stuxnet :) > conveniently "discovered" by a 3 letter agency favorite principle contractor Not sure what you are alluding to. 3LAs wouldn't want this to be known if it was their job, methinks.
