  "title": "Bluetooth: hci_conn: fix potential UAF in create_big_sync",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  Bluetooth: hci_conn: fix potential UAF in create_big_sync  Add hci_conn_valid() check in create_big_sync() to detect stale connections before proceeding with BIG creation. Handle the resulting -ECANCELED in create_big_complete() and re-validate the connection under hci_dev_lock() before dereferencing, matching the pattern used by create_le_conn_complete() and create_pa_complete().  Keep the hci_conn object alive across the async boundary by taking a reference via hci_conn_get() when queueing create_big_sync(), and dropping it in the completion callback. The refcount and the lock are complementary: the refcount keeps the object allocated, while hci_dev_lock() serializes hci_conn_hash_del()\u0027s list_del_rcu() on hdev-\u003Econn_hash, as required by hci_conn_del().  hci_conn_put() is called outside hci_dev_unlock() so the final put (which resolves to kfree() via bt_link_release) does not run under hdev-\u003Elock, though the release path would be safe either way.  Without this, create_big_complete() would unconditionally dereference the conn pointer on error, causing a use-after-free via hci_connect_cfm() and hci_conn_del().",
