The version of Containerd on the remote host is 2.0.1 prior to 2.0.5. It is, therefore, affected by a vulnerability. 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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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.

Note that Nessus relies on the presence of the package as reported by the vendor.
