✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: No mitigation is needed for Red Hat products. The vulnerable code path in containerd's CRI plugin group-parsing logic is not executed because Red Hat uses CRI-O as the container runtime. Products that bundle containerd as a library dependency for OCI image operations are not affected.
