CVE-2026-94603Hinoki check available

Sandbox bypass via image-controlled checkpoint restoration

Published Oct 13, 2026 · Updated Oct 13, 2026

Sandbox bypass in Podman's podman run command allows attackers to gain extra container privileges through crafted checkpoint images. ContainerRun treats the io.podman.annotations.checkpoint.runtime.name image annotation as a restoration trigger and substitutes checkpoint configuration for requested container restrictions. Exploitation requires an operator or workflow to launch an untrusted image with a rootful backend; rootless containers are unaffected, and the established consequence is loss of requested confinement rather than guaranteed host takeover.
