{"id":"CVE-2026-23411","summary":"apparmor: fix race between freeing data and fs accessing it","details":"In the Linux kernel, the following vulnerability has been resolved:\n\napparmor: fix race between freeing data and fs accessing it\n\nAppArmor was putting the reference to i_private data on its end after\nremoving the original entry from the file system. However the inode\ncan aand does live beyond that point and it is possible that some of\nthe fs call back functions will be invoked after the reference has\nbeen put, which results in a race between freeing the data and\naccessing it through the fs.\n\nWhile the rawdata/loaddata is the most likely candidate to fail the\nrace, as it has the fewest references. If properly crafted it might be\npossible to trigger a race for the other types stored in i_private.\n\nFix this by moving the put of i_private referenced data to the correct\nplace which is during inode eviction.","modified":"2026-04-03T11:02:20.878408Z","published":"2026-04-01T08:36:39.819Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23411.json","cna_assigner":"Linux"},"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/13bc2772414d68e94e273dea013181a986948ddf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2a732ed26fbd048e7925d227af8cf9ea43fb5cc9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8e135b8aee5a06c52a4347a5a6d51223c6f36ba3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ae10787d955fb255d381e0d5589451dd72c614b1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eecce026399917f6efa532c56bc7a3e9dd6ee68b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23411.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23411"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"c961ee5f21b202dea60b63eeef945730d92e46a6"},{"fixed":"ae10787d955fb255d381e0d5589451dd72c614b1"},{"fixed":"eecce026399917f6efa532c56bc7a3e9dd6ee68b"},{"fixed":"13bc2772414d68e94e273dea013181a986948ddf"},{"fixed":"2a732ed26fbd048e7925d227af8cf9ea43fb5cc9"},{"fixed":"8e135b8aee5a06c52a4347a5a6d51223c6f36ba3"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-23411.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.13.0"},{"fixed":"6.6.130"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.77"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.18"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-23411.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
