Description

The vulnerability allows a remote user to escalate privileges on the system.

The vulnerability exists due to the way CRI-O handles restoration of archive container. A remote user with access to the kubelet or cri-o socket can call the restore endpoint and trigger the restore.When restoration starts, the application will attempt to restore the mounts from the restore archive instead of the pod request and access host mounts.

Mitigation

Install updates from vendor's website.
