[Xen-devel] [PATCH v1 0/2] x86/vvmx: a couple of fixes (vmptrld + vmread/vmwrite)

[Sergey Dyasli <sergey.dyasli@xxxxxxxxxx>]

I have found 2 more ways to crash Xen from a guest with nested virt.
These patches implement some missing checks.

Sergey Dyasli (2):
  x86/vvmx: check vmcs address in vmread/vmwrite
  x86/vvmx: add vmcs id check into vmptrld emulation
