CVE ID:	CVE-2011-2512
Description:	The virtio_queue_notify in qemu-kvm 0.14.0 and earlier does not properly validate the virtqueue number, which allows guest users to cause a denial of service (guest crash) and possibly execute arbitrary code via a negative number in the Queue Notify field of the Virtio Header, which bypasses a signed comparison.
Test IDs:	1.3.6.1.4.1.25623.1.0.69978
