** Changed in: linux-lts-quantal (Ubuntu Precise)
       Status: New => Fix Committed

** Changed in: linux-lts-saucy (Ubuntu Precise)
       Status: New => Fix Committed

** Description changed:

  If the guest writes a noncanonical value to certain MSR registers, KVM
  will write that value to the MSR in the host context and a #GP will be
  raised leading to kernel panic. A privileged guest user can use this
  flaw to crash the host. Enabling CONFIG_PARAVIRT when building the
  kernel mitigates this issue because wrmsrl() ends up invoking safe msr
  write variant.
