✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: To mitigate the issue, we suggest upgrading to versions 5.9.0+ or 6.0.0-alpha.1+ 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. Workaround: For Red Hat OpenShift and layered products, CRI-O is the supported container runtime, so the vulnerable containerd CRI checkpoint-restore code path is not exercised during normal cluster operation. Customers should nevertheless apply Red Hat product errata as they become available to receive updates for affected operator, must-gather and tooling images that may bundle the containerd Go module. If containerd is deployed as the container runtime with CRI checkpoint/restore enabled, disable checkpoint/restore functionality until a fixed version of containerd can be applied.
