{"identifier":"CVE-2026-98862","cve":{"id":"CVE-2026-98862","description":"In the Linux kernel, the following vulnerability has been resolved:\n\naudit: fix exe mark UAF in kill_rules()\n\nkill_rules() removes mixed AUDIT_DIR and AUDIT_EXE rules when an audit\ntree is pruned. It drops entry->rule.exe before removing the rule from\nthe RCU-visible filter lists.\n\nAfter a rule has been installed with AUDIT_ADD_RULE, which requires\nCAP_AUDIT_CONTROL, removing the watched directory can race with another\ntask that is still evaluating the rule. In that case, fsnotify can free\nthe executable mark before the reader reaches audit_mark_compare(),\ncausing a use-after-free.\n\nKASAN reports:\n\n    BUG: KASAN: slab-use-after-free in audit_mark_compare+0x8d/0xa0\n\nUnlink the published rules from the RCU-visible lists and retain them\non tree->rules for cleanup. If any rule has an executable mark, wait for\na single RCU grace period before removing the marks and scheduling the\nentries for freeing. Otherwise, call_rcu() already provides the required\ndeferred freeing without a synchronous wait.","published":"2026-10-18T16:17:40.677000+00:00","modified":"2026-10-21T13:21:50.443000+00:00","status":"Received","score":null,"severity":"UNSCORED","vector":"","cvss_version":"","affected":[],"weaknesses":[],"references":[{"url":"https://git.kernel.org/stable/c/304960900991157e6883bdf0b39782b690545ee8","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/88633025f20ba9c32ccdb3efc86eafdf98cb825c","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/9aee3caeff4dd4126d84f67607b95cec8719b867","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/aa650d87a498844060eecb1d336f4d46f4d1b0b3","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/f2cc5462b78559c7628a9f8ac9a9592e7783183a","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"}],"kev":null,"kev_checked":true,"metrics":{},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T10:23:33.085855+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00157,"percentile":0.04781,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"git.kernel.org","source_url":"https://git.kernel.org/stable/c/304960900991157e6883bdf0b39782b690545ee8","investigate_url":"https://investigate.aeglixmind.com/#git.kernel.org"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-98862","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-98862","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-98862","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
