CVE-2011-2512

Summary

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.

Vulnerable Systems

Application

  • Kvm Group Qemu-kvm 0.12

  • Kvm Group Qemu-kvm 0.14.0
