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fails.","score":8.8,"severity":"high","published":"2026-10-18T15:15:01.473Z","modified":"2026-10-30T12:38:11.067Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"d2c127197dfc0b2bae62a52e1e0d3e3ff493919e","status":"affected","lessThan":"bc585d5a381ab49cb611c35dda93a997214ca874","versionType":"git"},{"version":"d2c127197dfc0b2bae62a52e1e0d3e3ff493919e","status":"affected","lessThan":"26f4bca335e719e291995e28dc434de0145a6a54","versionType":"git"},{"version":"d2c127197dfc0b2bae62a52e1e0d3e3ff493919e","status":"affected","lessThan":"51c7b0593f6eaba05349fd2a01a9cb4df7d7412f","versionType":"git"},{"version":"d2c127197dfc0b2bae62a52e1e0d3e3ff493919e","status":"affected","lessThan":"045532f920d86dd76600b635f9756e5fd671ddfc","versionType":"git"},{"version":"d2c127197dfc0b2bae62a52e1e0d3e3ff493919e","status":"affected","lessThan":"ed03d547598c92a036f20e89156540995cac889a","versionType":"git"},{"version":"d2c127197dfc0b2bae62a52e1e0d3e3ff493919e","status":"affected","lessThan":"70a7918fda54a06d836acc91eb9a3c7e860fe0a0","versionType":"git"},{"version":"d2c127197dfc0b2bae62a52e1e0d3e3ff493919e","status":"affected","lessThan":"3c07deb26273155c180aedfd9041ab58015d2521","versionType":"git"},{"version":"d2c127197dfc0b2bae62a52e1e0d3e3ff493919e","status":"affected","lessThan":"e66cf1625ec4a3fe68346119f371def713fd0a4d","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98451"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"3.6","status":"affected"},{"version":"0","status":"unaffected","lessThan":"3.6","versionType":"semver"},{"version":"5.10.273","status":"unaffected","lessThanOrEqual":"5.10.*","versionType":"semver"},{"version":"5.15.224","status":"unaffected","lessThanOrEqual":"5.15.*","versionType":"semver"},{"version":"6.1.191","status":"unaffected","lessThanOrEqual":"6.1.*","versionType":"semver"},{"version":"6.6.160","status":"unaffected","lessThanOrEqual":"6.6.*","versionType":"semver"},{"version":"6.12.113","status":"unaffected","lessThanOrEqual":"6.12.*","versionType":"semver"},{"version":"6.18.56","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.9","status":"unaffected","lessThanOrEqual":"7.2.*","versionType":"semver"},{"version":"7.3","status":"unaffected","lessThanOrEqual":"*","versionType":"original_commit_for_fix"}],"defaultStatus":"affected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98451"}],"remediation":[],"references":["https://git.kernel.org/stable/c/bc585d5a381ab49cb611c35dda93a997214ca874","https://git.kernel.org/stable/c/26f4bca335e719e291995e28dc434de0145a6a54","https://git.kernel.org/stable/c/51c7b0593f6eaba05349fd2a01a9cb4df7d7412f","https://git.kernel.org/stable/c/045532f920d86dd76600b635f9756e5fd671ddfc","https://git.kernel.org/stable/c/ed03d547598c92a036f20e89156540995cac889a","https://git.kernel.org/stable/c/70a7918fda54a06d836acc91eb9a3c7e860fe0a0","https://git.kernel.org/stable/c/3c07deb26273155c180aedfd9041ab58015d2521","https://git.kernel.org/stable/c/e66cf1625ec4a3fe68346119f371def713fd0a4d"],"sources":[{"name":"CVE","id":"CVE-2026-98451","modified":"2026-10-30T12:38:11.067Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98451"}],"assessments":[{"source":"Linux","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8}],"sourceAffected":[],"observedAt":"2026-10-30T14:01:26.212Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T23:50:31.991Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
