An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system.","published":"2022-02-11T18:15:10.890Z","modified":"2026-04-16T04:38:12.026387006Z","cvss":{"score":8.4,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.25151,"percentile":0.9777,"asOf":"2026-08-27"},"cisaKev":{"dateAdded":"2024-08-21","dueDate":"2024-09-11","knownRansomwareCampaignUse":false},"exploitsKnown":15,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2022-0185"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20220225-0003/"},{"type":"FIX","url":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=722d94847de2"},{"type":"FIX","url":"https://www.openwall.com/lists/oss-security/2022/01/18/7"},{"type":"EVIDENCE","url":"https://github.com/Crusaders-of-Rust/CVE-2022-0185"},{"type":"EVIDENCE","url":"https://www.willsroot.io/2022/01/cve-2022-0185.html"}],"provenance":{"sources":["OSV.dev","CISA KEV","FIRST.org (EPSS)"],"lastVerified":"2026-04-16T04:38:12.026387006Z"}}
