Name of the Vulnerable Software and Affected Versions containerd versions 2.0.1 through 2.0.4

Description A bug was found in containerd's CRI implementation where it doesn't put usernamespaced containers under the Kubernetes' cgroup hierarchy, causing some Kubernetes limits to not be honored. This may lead to a denial of service of the Kubernetes node.

Recommendations For containerd versions 2.0.1 through 2.0.4, update to version 2.0.5 or later, or 2.1.0 or later, to resolve the issue. As a temporary workaround, consider disabling usernamespaced pods in Kubernetes until the issue is resolved.
