{"schema":"threatline.record/2","record":{"id":"CVE-2026-53614","aliases":["GHSA-67r7-8m5w-22wx"],"summary":"util-linux LIBMOUNT_FORCE_MOUNT2 allows nosuid and noexec bypass","details":"util-linux is a random collection of Linux utilities. In util-linux 2.39.1 through 2.41.4 and 2.42 through 2.42.1, the SUID `mount` utility reads the attacker-controlled `LIBMOUNT_FORCE_MOUNT2` environment variable with `getenv()`, allowing a local low-privileged\nuser to force the non-atomic legacy bind-mount path. With an `/etc/fstab` bind mount authorized by `user` or `users` and protected by `nosuid`, `noexec`, or `nodev`, an attacker can race the window between the initial bind mount and the remount that applies those security flags and execute a SUID program from the temporarily unprotected mount, potentially gaining root privileges. This issue is fixed in 2.41.5 and 2.42.2.","categories":["Unclassified"],"product":"util-linux","vendor":"util-linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-53614","source_modified_at":"2026-10-15T15:08:08.295Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"util-linux","vendor":"util-linux","versions":[{"status":"affected","version":">= 2.39.1, < 2.41.5"},{"status":"affected","version":">= 2.42, < 2.42.2"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/util-linux/util-linux/security/advisories/GHSA-67r7-8m5w-22wx","source_modified_at":"2026-08-31T12:32:36Z","fetched_at":"2026-10-24T14:26:37.433577Z","package":{"ecosystem":"","name":"util-linux"},"range":">= 2.39.1"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/util-linux/util-linux/security/advisories/GHSA-67r7-8m5w-22wx","source_modified_at":"2026-08-31T12:32:36Z","fetched_at":"2026-10-24T14:26:37.433577Z","package":{"ecosystem":"","name":"util-linux"},"version":"2.41.5; 2.42.2"}],"cvss":7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00139,"percentile":0.02978,"score_date":"2026-10-23"},"published_at":"2026-10-14T15:40:53.674Z","modified_at":"2026-10-15T15:08:08.295Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-53614","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T15:08:08.295Z"},{"source":"GitHub Advisory Database","url":"https://github.com/util-linux/util-linux/security/advisories/GHSA-67r7-8m5w-22wx","fetched_at":"2026-10-24T14:26:37.433577Z","source_modified_at":"2026-08-31T12:32:36Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-53614","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/util-linux/util-linux/security/advisories/GHSA-67r7-8m5w-22wx","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/util-linux/util-linux/commit/31e37c1c7dcf25b76ccf41391fe934a75644c661","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/util-linux/util-linux/commit/53ff0fcdab12d69c60c971c69a3d0d173fa46ca9","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/util-linux/util-linux/commit/9cbfb823500f510b34767edabd3ffd5b436987b4","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/util-linux/util-linux/commit/cc81bbcec598cb91f0eb8456282f33eed820ed5f","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/util-linux/util-linux/commit/fd6b4d94ff013dc7ed680d4e864610da5b9751f1","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/util-linux/util-linux/releases/tag/v2.41.5","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/util-linux/util-linux/releases/tag/v2.42.2","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-15T13:11:43.965210Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T15:08:08.295Z","content_hash":"53929516b812bf543d51386e56eca96d574ed6f6fcd86266bc07d4890f65b9b3"}}
