A vulnerability, which was classified as problematic, was found in containerd up to 2.0.4. Affected is an unknown function. The manipulation with an unknown input leads to a privileges assignment vulnerability. CWE is classifying the issue as CWE-266. A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor. This is going to have an impact on availability. CVE summarizes:

containerd is an open-source container runtime. A bug was found in the containerd's CRI implementation where containerd, starting in version 2.0.1 and prior to version 2.0.5, doesn't put usernamespaced containers under the Kubernetes' cgroup hierarchy, therefore some Kubernetes limits are not honored. This may cause a denial of service of the Kubernetes node. This bug has been fixed in containerd 2.0.5+ and 2.1.0+. Users should update to these versions to resolve the issue. As a workaround, disable usernamespaced pods in Kubernetes temporarily.
