A non-root user can bypass mount security restrictions set in /etc/fstab by specifying clearing-mask options on the command line. These options pass the non-root flag filter and are merged with fstab options as strings; when the combined options are re-parsed, clearing options can override nosuid, nodev, and noexec protections the administrator intended to enforce.","state":0,"publishedAt":"2026-10-13T16:56:15.518+00:00","modifiedAt":"2026-10-14T16:16:14.045+00:00","affected":[{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"busybox","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Hardened Images\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"busybox\",\n                    \"defaultStatus\": \"affected\",\n                    \"cpes\": [\n                        \"cpe:/a:redhat:hummingbird:1\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":5.5,"severity":"MEDIUM"}],"references":["https://access.redhat.com/security/cve/CVE-2026-88838","https://bugzilla.redhat.com/show_bug.cgi?id=2531352"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-88838","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-88838","identifiers":["CVE-2026-88838"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
