**Name of the Vulnerable Software and Affected Versions** QEMU (affected versions not specified) **Description** The issue is related to the Virtio Vring implementation in QEMU, which allows local OS guest users to cause a denial of service. This can be achieved by unsetting vring alignment while updating Virtio rings, resulting in a divide-by-zero error and a QEMU process crash. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
