CVE-2026-94603 is a sandbox bypass vulnerability in Podman's handling of container images carrying checkpoint annotations. When such an image is executed with podman run, Podman treats it as a restored checkpoint and ignores user-specified sandboxing options, including dropped privileges. An attacker can entice a user to execute a specially crafted image, potentially allowing execution with elevated system privileges.
