CVE-2026-95837Hinoki check available

Privilege escalation via checkpoint security-context bypass

Published Oct 12, 2026 · Updated Oct 12, 2026

Privilege escalation in containerd's CRI CreateContainer allows local users to run as root via crafted checkpoint data. CRIU restores credentials, capabilities, no_new_privs, and seccomp state from the checkpoint instead of enforcing the destination ContainerConfig. Exploitation requires container creation access and Linux CRI checkpoint restore; processes gain full capabilities without enforced seccomp filters while CRI status reports the requested restrictions.
