Containerd 2.1.x < 2.1.9 / 2.2.x < 2.2.5 / 2.3.x < 2.3.2 Multiple Vulnerabilities

Synopsis

The container runtime installed on the remote host is affected by multiple vulnerabilities.

Description

The version of Containerd on the remote host is 2.1.x prior to 2.1.9, 2.2.x prior to 2.2.5, or 2.3.x prior to 2.3.2.
It is, therefore, affected by multiple vulnerabilities:

 - containerd's CRI checkpoint import process contains a vulnerability where it fails to validate the image references specified within a checkpoint image's configuration. An attacker with permissions to create pods can use a crafted checkpoint image to force containerd to pull a malicious image and assign it an arbitrary local tag, thereby poisoning the node's local image cache. (CVE-2026-50195)

 - A bug was found in containerd where the CRI plugin restores container.log from a checkpoint image without validating a symlinked path. This could result in reading an arbitrary file on the host via kubectl logs.
 (CVE-2026-53489)

 - containerd's CRI implementation improperly trusts Container Device Interface (CDI) annotations found within untrusted checkpoint image metadata during container restoration. When restoring a container from a checkpoint, containerd preserves CDI-related annotations from the checkpoint archive rather than relying solely on the pod's create-time specification. This allows a user with pod creation permissions to bypass standard Kubernetes resource allocation and device plugin enforcement, injecting arbitrary CDI edits into the restored container.
 (CVE-2026-53492)

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

Solution

Upgrade to Containerd version 2.1.9, 2.2.5, 2.3.2 or later.
