The instruction decoder in arch/x86/kvm/emulate.c in the KVM subsystem in
the Linux kernel before 3.18-rc2 does not properly handle invalid
instructions, which allows guest OS users to cause a denial of service
(NULL pointer dereference and host OS crash) via a crafted application that
triggers (1) an improperly fetched instruction or (2) an instruction that
occupies too many bytes. NOTE: this vulnerability exists because of an
incomplete fix for CVE-2014-8480.
