This allows the main processes of the container, if running as root, to gain access to file-descriptors of these new processes during the initialization and can lead to container escapes or modification of runC state before the process is fully placed inside the container.","published":"2017-01-31T22:59:02.000Z","lastModified":"2026-06-17T00:56:51.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":6.4,"severity":"MEDIUM","vector":"CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-362"],"affected":["docker/docker"],"epss":{"score":0.00412,"percentile":0.35254,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.41%).
