NVD description

containerd is an open-source container runtime. In Versions prior to 2.3.2, 2.2.5 and 2.1.9, the 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 (such as device nodes and host mounts) into the restored container. Successful exploitation requires that the node has CDI enabled and contains a matching host CDI specification for the requested device; environments where CDI is disabled or lacking sensitive device specifications are not affected. This issue has been fixed in versions 2.3.2, 2.2.5 and 2.1.9.

    🚨Critical - containerd CRI Plugin Multiple Vulnerabilities (CVE-2026-50195, CVE-2026-53488, CVE-2026-53492, CVE-2026-53489, CVE-2026-47262) AWS disclosed five flaws in the containerd CRI plugin (v1.7–2.3), the runtime behind EKS, ECS, Fargate, GKE and self-managed Kubernetes. Most are reachable by an attacker who only has permission to create pods on a shared node. The headline bug lets a crafted checkpoint image poison the node's local image cache so other pods unknowingly run the attacker's image — cross-pod code execution. Even nastier: unsanitized image LABEL instructions reach the restart-monitor binary:// logger, giving host-root command execution straight from an image pull, with no checkpoint/restore required. The rest cover CDI annotation smuggling (device/host-mount injection), arbitrary host file read via symlinked log paths, and an image-triggered OOM DoS. 👉Upgrade to containerd 2.3.2 / 2.2.5 / 2.1.9.

    Post summary

    AWS disclosed five critical vulnerabilities in containerd CRI plugin, detailing how attackers can achieve cross‑pod and host‑root execution, along with a patch recommendation.
