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.
