CVE-2024-8676: Cri-o: checkpoint restore can be triggered from different namespaces

A vulnerability was found in CRI-O, where it can be requested to take a checkpoint archive of a container and later be asked to restore it. When it does that restoration, it attempts to restore the mounts from the restore archive instead of the pod request. As a result, the validations run on the pod spec, verifying that the pod has access to the mounts it specifies are not applicable to a restored container. This flaw allows a malicious user to trick CRI-O into restoring a pod that doesn't have access to host mounts. The user needs access to the kubelet or cri-o socket to call the restore endpoint and trigger the restore.

Security readout for executives and security teams

Plain-English summary

CVE-2024-8676 lets CRI-O restore a container checkpoint using mounts from the archive, bypassing pod mount validation. If an attacker can reach the kubelet or CRI-O socket, they may restore a pod with unauthorized host mounts, risking host data exposure or modification.

Executive priority

Prioritize remediation for OpenShift or Kubernetes environments with shared administration, multi-tenant workloads, or broad node socket access. This is not reported as actively exploited, but unauthorized host mount access can materially affect confidentiality and integrity.

Technical view

The flaw is an authorization bypass in CRI-O checkpoint restore. During restore, CRI-O validates the requested pod spec but restores mount definitions from the checkpoint archive. That mismatch can permit host mounts not authorized for the pod. Red Hat rates it high, CVSS 7.4, CWE-285.

Likely exposure

Highest concern is Kubernetes/OpenShift nodes where untrusted users, workloads, or automation can access the kubelet or CRI-O socket. Red Hat lists affected OpenShift 4.15, 4.16, 4.17, 4.18 components and some RHEL container packages. Product status varies by package and advisory.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. Exploitation requires access to the kubelet or CRI-O socket and ability to trigger the restore endpoint, making socket exposure and node-level access controls central to risk.

Researcher notes

Key issue is validation confusion between pod spec mounts and checkpoint archive mounts during restore. Do not assume network-only exposure; practical exploitability depends on access to kubelet or CRI-O socket. Red Hat package impact is nuanced, so validate by advisory and installed package.

Mitigation direction

  • Apply applicable Red Hat errata for affected OpenShift, RHCOS, and RHEL container packages.
  • Review Red Hat CVE guidance for exact package status and fixed builds.
  • Restrict kubelet and CRI-O socket access to trusted node components only.
  • Disable or tightly control checkpoint/restore workflows where not operationally required.

Validation and detection

  • Inventory OpenShift, RHCOS, CRI-O, podman, and conmon versions against Red Hat advisories.
  • Confirm affected nodes have received the relevant Red Hat security or bugfix errata.
  • Verify untrusted users and workloads cannot access kubelet or CRI-O sockets.
  • Review cluster policies governing checkpoint and restore capability usage.
