NVD Description

Note: Versions mentioned in the description apply only to the upstream olcne-oci-ccm-chart package and not the olcne-oci-ccm-chart package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor'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.
