WARNING: possible circular locking dependency detected

syz-executor.4/23292 is trying to acquire lock:

other info that might help us debug this:

Chain exists of:
  &ovl_i_mutex_key[depth] --> &p->lock --> &sig->cred_guard_mutex

 Possible unsafe locking scenario:

       CPU0                    CPU1
