AnalysisAI

Checkpoint image poisoning in containerd's CRI implementation allows an attacker with pod-creation permissions to corrupt the node-local image cache, causing victim pods to silently execute malicious images in place of legitimate ones. The root cause is missing validation of image references embedded in checkpoint image configurations: containerd trusts attacker-controlled strings in the checkpoint archive to drive image pulls and local tag assignment. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Obtain pod-creation RBAC permissions
Delivery
Craft malicious OCI checkpoint image with forged image references
Exploit
Submit pod triggering CRI checkpoint import
Execution
containerd pulls malicious image and assigns attacker-chosen local tag
Persist
Victim pod schedules to poisoned node with IfNotPresent or Never pull policy
Impact
Victim pod executes malicious image under its own Kubernetes service account identity

Vulnerability AssessmentAI

Exploitation The attacker must hold Kubernetes RBAC permissions sufficient to create pods in at least one namespace on the target cluster - specifically the ability to invoke the CRI checkpoint import path (e.g., via the kubelet checkpoint API or equivalent). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment No CVSS vector or EPSS score is present in the provided data, so quantitative risk metrics cannot be cited - severity is vendor-stated as Critical via GHSA-cvxm-645q-p574. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with Kubernetes pod-creation RBAC permissions on a target namespace builds a malicious OCI checkpoint image that embeds forged image reference strings pointing to attacker-controlled registry content. They submit a pod spec that triggers containerd's CRI checkpoint import path, causing containerd to fetch the malicious image and register it locally under a tag matching a legitimate image expected by other workloads on the same node. …
Remediation Update containerd to a patched release: 2.3.2, 2.2.5, or 2.1.9, available at https://github.com/containerd/containerd/releases. … Detailed patch versions, workarounds, and compensating controls in full report.
