CVE-2011-2512
5.8 · MEDIUMOverview
CVE-2011-2512 is a medium-severity vulnerability affecting kvm_group qemu-kvm. It was published on June 21, 2012 and has a CVSS 2.0 base score of 5.8 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 5.8, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from kvm_group. Update qemu-kvm to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
