Bug description:
  The WRMSR processing functionality in the KVM subsystem in the Linux
  kernel through 3.17.2 does not properly handle the writing of a non-
  canonical address to a model-specific register, which allows guest OS
  users to cause a denial of service (host OS crash) by leveraging guest
  OS privileges, related to the wrmsr_interception function in
  arch/x86/kvm/svm.c and the handle_wrmsr function in
  arch/x86/kvm/vmx.c. 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.

  Break-Fix: - 854e8bb1aa06c578c2c9145fa6bfe3680ef63b23
