AI-suggested
There is currently no complete workaround. Until a vendor patch is available, administrators should restrict pod creation and updates that allow setting arbitrary annotations via RBAC and admission policies. Minimizing unnecessary CRI-O restarts or node reboots reduces exposure windows. Monitoring for anomalous container mounts, such as unexpected mounts under /dev/shm following runtime restarts, is recommended. Apply the official vendor patch once it is released to fully remediate the vulnerability.
Description
CVE-2026-62146 is a trust-boundary vulnerability in CRI-O's sandbox state persistence used by Red Hat OpenShift Container Platform 4.16. It allows attacker-controlled pod metadata to overwrite CRI-O's reserved sandbox bookkeeping data. After a CRI-O restart, this corrupted state is trusted, enabling a container recreate operation to expose a host-side runtime-management resource inside the container, leading to container escape.
