** Description changed:

- IA32_VMX_EPT_VPID_CAP MSR is set) guest invocation of invvpid causes vm
- exit, which is currently not handled and causes unknown exit error to be
- propagated to userspace. A local unprivileged guest user could use this
+ arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel through
+ 3.17.2 does not have an exit handler for the INVVPID instruction, which
+ allows guest OS users to cause a denial of service (guest OS crash) via
+ a crafted application. A local unprivileged guest user could use this
  flaw to crash the guest.

Bug description:
  arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel through
  3.17.2 does not have an exit handler for the INVVPID instruction,
  which allows guest OS users to cause a denial of service (guest OS
  crash) via a crafted application. A local unprivileged guest user
  could use this flaw to crash the guest.
