"value": "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."
