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":"2022-02-11T17:40:57Z","modified":"2026-10-21T02:45:54.881119112Z","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":0.97802,"asOf":"2026-09-11"},"cisaKev":null,"exploitsKnown":15,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=722d94847de2"},{"type":"WEB","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2022-0185"},{"type":"WEB","url":"https://www.openwall.com/lists/oss-security/2022/01/18/7"},{"type":"WEB","url":"https://www.willsroot.io/2022/01/cve-2022-0185.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/0xxx/CVE-2022-0185.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-0185"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20220225-0003/"},{"type":"PACKAGE","url":"https://github.com/Crusaders-of-Rust/CVE-2022-0185"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-21T02:45:54.881119112Z"}}
