  "title": "audit: fix exe mark UAF in kill_rules()",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  audit: fix exe mark UAF in kill_rules()  kill_rules() removes mixed AUDIT_DIR and AUDIT_EXE rules when an audit tree is pruned. It drops entry-\u003Erule.exe before removing the rule from the RCU-visible filter lists.  After a rule has been installed with AUDIT_ADD_RULE, which requires CAP_AUDIT_CONTROL, removing the watched directory can race with another task that is still evaluating the rule. In that case, fsnotify can free the executable mark before the reader reaches audit_mark_compare(), causing a use-after-free.  KASAN reports:      BUG: KASAN: slab-use-after-free in audit_mark_compare\u002B0x8d/0xa0  Unlink the published rules from the RCU-visible lists and retain them on tree-\u003Erules for cleanup. If any rule has an executable mark, wait for a single RCU grace period before removing the marks and scheduling the entries for freeing. Otherwise, call_rcu() already provides the required deferred freeing without a synchronous wait.",
