--------------------------------------------
syz-executor.0/5443 is trying to acquire lock:
ffffffff8e23db98 (qp_broker_list.mutex){+.+.}-{3:3}, at: vmci_qp_broker_detach+0xf5/0x1210 drivers/misc/vmw_vmci/vmci_queue_pair.c:2095

but task is already holding lock:

other info that might help us debug this:
 Possible unsafe locking scenario:

       CPU0
       ----
  lock(qp_broker_list.mutex);
  lock(qp_broker_list.mutex);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
