An attacker can trigger a Denial of Service (DoS) by supplying a container image containing crafted metadata labels. Podman's auto-update mechanism improperly trusts these image labels to determine which system services to restart. If a user runs the malicious container and auto-update processes it, arbitrary system services are restarted with the user's privileges, potentially allowing an attacker to shut down the host system when Podman runs with administrative privileges.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-807"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-121885","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2566844","tags":[]},{"url":"https://github.com/podman-container-tools/podman/security/advisories/GHSA-55rm-rwr7-q2wr","tags":[]}],"exploitRefs":[{"url":"https://github.com/podman-container-tools/podman/security/advisories/GHSA-55rm-rwr7-q2wr","tags":[]}],"hasPoc":true,"ai":null}
