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.","state":0,"publishedAt":"2026-10-14T15:40:53.674+00:00","modifiedAt":"2026-10-15T15:08:08.295+00:00","affected":[{"ecosystem":"Vendor product","name":"util-linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"util-linux\",\n                    \"product\": \"util-linux\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.39.1, < 2.41.5\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.42, < 2.42.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7,"severity":"HIGH"}],"references":["https://github.com/util-linux/util-linux/security/advisories/GHSA-67r7-8m5w-22wx","https://github.com/util-linux/util-linux/commit/31e37c1c7dcf25b76ccf41391fe934a75644c661","https://github.com/util-linux/util-linux/commit/53ff0fcdab12d69c60c971c69a3d0d173fa46ca9","https://github.com/util-linux/util-linux/commit/9cbfb823500f510b34767edabd3ffd5b436987b4","https://github.com/util-linux/util-linux/commit/cc81bbcec598cb91f0eb8456282f33eed820ed5f","https://github.com/util-linux/util-linux/commit/fd6b4d94ff013dc7ed680d4e864610da5b9751f1","https://github.com/util-linux/util-linux/releases/tag/v2.41.5","https://github.com/util-linux/util-linux/releases/tag/v2.42.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-53614","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-53614","identifiers":["CVE-2026-53614"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
