{"id":"CVE-2026-98413","summary":"selinux: always fill AVC decision in avc_has_perm_noaudit()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nselinux: always fill AVC decision in avc_has_perm_noaudit()\n\navc_has_perm_noaudit() is documented to return a copy of the access\ndecision in @avd, but its early return for an empty requested permission\nset leaves the buffer untouched.  All callers pass an uninitialized\nstack variable and afterwards feed it to avc_audit(), and the inode hook\neven stores it in the per-task decision cache.\n\nFill in a deny-all, audit-all decision, similar to avd_init(), so every\ncaller receives a defined value at no cost on the hot path.","modified":"2026-10-15T02:47:42.621547891Z","published":"2026-10-14T13:27:45.404Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98413.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/24e00850bcff46b984f4c44b92e5499450fcfb5a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5a6f9a872b4ff68877caf998bee352153b7154bc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/835133337c2ce200db56f62d018c79087dee2603"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8861db305103107199b1426f25fde1fb6d465583"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c781e737aa0de95289b1774d5fd29388895737a9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e308c5acfe283a66627fc407065626df4ab753ec"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e77461af13eab5c9a953cc52ec8432cc941d61e2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f9da796fa238f8e4414ee8481e6c979759a3d563"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98413.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98413"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e6f2f381e4015386a656a369835f949c26000e6b"},{"fixed":"c781e737aa0de95289b1774d5fd29388895737a9"},{"fixed":"e308c5acfe283a66627fc407065626df4ab753ec"},{"fixed":"f9da796fa238f8e4414ee8481e6c979759a3d563"},{"fixed":"e77461af13eab5c9a953cc52ec8432cc941d61e2"},{"fixed":"5a6f9a872b4ff68877caf998bee352153b7154bc"},{"fixed":"24e00850bcff46b984f4c44b92e5499450fcfb5a"},{"fixed":"835133337c2ce200db56f62d018c79087dee2603"},{"fixed":"8861db305103107199b1426f25fde1fb6d465583"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98413.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.1.0"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.54"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98413.json"}}],"schema_version":"1.9.0"}
