It could occur when the descriptor&#39;s address belongs to the non direct access region, due to num_buffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting in a denial of service condition, or potentially execute code on the host with the privileges of the QEMU process.</p> <p><strong>Affected:</strong> QEMU (virtio-net)</p> <p>A use-after-free vulnerability was found in the virtio-net device of QEMU.
