## Overview

In the Linux kernel, the following vulnerability has been resolved:

KVM: SVM: Don't BUG if userspace injects an interrupt with GIF=0

Don't BUG/WARN on interrupt injection due to GIF being cleared,
since it's trivial for userspace to force the situation via
KVM_SET_VCPU_EVENTS (even if having at least a WARN there would be correct
for KVM internally generated injections).
