{"id":"CVE-2026-121885","summary":"Podman: untrusted image labels allow auto-update to restart arbitrary systemd units","details":"A flaw was found in Podman. 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.","aliases":["GHSA-55rm-rwr7-q2wr"],"modified":"2026-11-13T02:46:35.652843711Z","published":"2026-11-10T14:34:31.734Z","database_specific":{"cna_assigner":"redhat","cwe_ids":["CWE-807"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/121xxx/CVE-2026-121885.json"},"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-121885"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/121xxx/CVE-2026-121885.json"},{"type":"ADVISORY","url":"https://github.com/podman-container-tools/podman/security/advisories/GHSA-55rm-rwr7-q2wr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-121885"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2566844"},{"type":"PACKAGE","url":"https://github.com/podman-container-tools/podman"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/podman-container-tools/podman","events":[{"introduced":"028e3317eb1494b9b2acba4a0a295df80fae66cc"},{"fixed":"eacf7fc89d8980899f687f53f657ae40e2597954"},{"introduced":"a8ed4b6dd12992decf659cadfdfb3d0cb1937748"},{"fixed":"055de046937d29450f310fce0fe3071485d8bed9"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"1.8.2"},{"fixed":"5.8.10"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"},{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"6.0.0"},{"fixed":"6.2.0"}]}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-121885.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
