  - Bluetooth: hci_sync: Fix UAF in hci_disconnect_all_sync Use-after-free can occur in     hci_disconnect_all_sync if a connection is deleted by concurrent processing of a controller event. To     prevent this the code now tries to iterate over the list backwards to ensure the links are cleanup before     its parents, also it no longer relies on a cursor, instead it always uses the last element since     hci_abort_conn_sync is guaranteed to call hci_conn_del.
