Vulnerability from cvelistv5 – Published: 2012-06-21 15:00 – Updated: 2024-08-06 23:00
VLAI?
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.
Severity ?
No CVSS data available.
