{"schema":"threatline.record/2","record":{"id":"CVE-2026-98451","aliases":[],"summary":"smb: client: use finish_no_open() for non-regular inodes","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: use finish_no_open() for non-regular inodes\n\nAn O_CREAT open can find an existing symlink or another non-regular\ninode. cifs_atomic_open() calls finish_open() on it and attaches a\ncifsFileInfo. Symlink inodes have no CIFS release operation, so the\ndentry reference held by cifsFileInfo is leaked. FMODE_OPENED also\nprevents the VFS from following the symlink.\n\nTrack whether cifs_do_create() returned an open server handle. For\nnon-regular inodes, close the handle if present, remove the pending\nopen, and call finish_no_open() so the VFS can continue the lookup.\nDo not set FMODE_CREATED unless a regular file was opened. For\nO_NOFOLLOW with __O_REGULAR, return -ELOOP before the VFS's\n-EFTYPE check.\n\nDefer closing a legacy POSIX handle on a non-regular inode until\nafter inode lookup. This avoids closing it again if lookup fails.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98451","source_modified_at":"2026-10-24T14:08:53.021Z","fetched_at":"2026-10-24T14:26:37.433577Z","product":"Linux","vendor":"Linux","versions":[{"version":"d2c127197dfc0b2bae62a52e1e0d3e3ff493919e","lessThan":"045532f920d86dd76600b635f9756e5fd671ddfc","status":"affected","versionType":"git"},{"version":"d2c127197dfc0b2bae62a52e1e0d3e3ff493919e","lessThan":"ed03d547598c92a036f20e89156540995cac889a","status":"affected","versionType":"git"},{"version":"d2c127197dfc0b2bae62a52e1e0d3e3ff493919e","lessThan":"70a7918fda54a06d836acc91eb9a3c7e860fe0a0","status":"affected","versionType":"git"},{"version":"d2c127197dfc0b2bae62a52e1e0d3e3ff493919e","lessThan":"3c07deb26273155c180aedfd9041ab58015d2521","status":"affected","versionType":"git"},{"version":"d2c127197dfc0b2bae62a52e1e0d3e3ff493919e","lessThan":"e66cf1625ec4a3fe68346119f371def713fd0a4d","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98451","source_modified_at":"2026-10-24T14:08:53.021Z","fetched_at":"2026-10-24T14:26:37.433577Z","product":"Linux","vendor":"Linux","versions":[{"version":"3.6","status":"affected"},{"version":"0","lessThan":"3.6","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.113","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.56","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.9","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98451","source_modified_at":"2026-10-24T14:08:53.021Z","fetched_at":"2026-10-24T14:26:37.433577Z","package":{"name":"Linux","ecosystem":null},"version":"045532f920d86dd76600b635f9756e5fd671ddfc","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98451","source_modified_at":"2026-10-24T14:08:53.021Z","fetched_at":"2026-10-24T14:26:37.433577Z","package":{"name":"Linux","ecosystem":null},"version":"70a7918fda54a06d836acc91eb9a3c7e860fe0a0","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98451","source_modified_at":"2026-10-24T14:08:53.021Z","fetched_at":"2026-10-24T14:26:37.433577Z","package":{"name":"Linux","ecosystem":null},"version":"3c07deb26273155c180aedfd9041ab58015d2521","basis":"first unaffected version stated in the CVE record"}],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.05727,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:15:01.473Z","modified_at":"2026-10-24T14:08:53.021Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98451","fetched_at":"2026-10-24T14:26:37.433577Z","source_modified_at":"2026-10-24T14:08:53.021Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98451","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/045532f920d86dd76600b635f9756e5fd671ddfc"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/ed03d547598c92a036f20e89156540995cac889a"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/70a7918fda54a06d836acc91eb9a3c7e860fe0a0"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/3c07deb26273155c180aedfd9041ab58015d2521"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/e66cf1625ec4a3fe68346119f371def713fd0a4d"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-24T14:08:53.021Z","content_hash":"1ebdcd36f888fdf70a6490b5387464d0d6eed379a9f9fc76d317bcd1bd31e9a7"}}
