A jailed process could rename a directory relative to a restricted descriptor, then escape the jail root via fchdir(2).  This requires the directory to reside on a filesystem that is also reachable from the jail's root.\n\nA process in a jail that has received a directory file descriptor from another jail can use these techniques to escape the jail's filesystem root restriction.","categories":["Operating systems"],"product":"FreeBSD","vendor":"FreeBSD","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101305","source_modified_at":"2026-10-16T18:30:32.048Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"FreeBSD","vendor":"FreeBSD","versions":[{"status":"affected","versionType":"release","version":"15.1-RELEASE","lessThan":"p4"},{"status":"affected","versionType":"release","version":"15.0-RELEASE","lessThan":"p14"},{"status":"affected","versionType":"release","version":"14.5-RELEASE","lessThan":"p1"},{"status":"affected","versionType":"release","version":"14.4-RELEASE","lessThan":"p10"}],"defaultStatus":"unknown"}],"fixed_versions":[],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00417,"percentile":0.34971,"score_date":"2026-10-23"},"published_at":"2026-10-15T06:46:16.471Z","modified_at":"2026-10-16T18:30:32.048Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-101305","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T18:30:32.048Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-101305","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://security.freebsd.org/advisories/FreeBSD-SA-26:66.jail.asc","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-16T18:30:17.230798Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-16T18:30:32.048Z","content_hash":"6eaf21688d367f8123f9a3b54e6f274a8813704f87f0b49a4ede065fd0a42f0e"}}
