In the Linux kernel, the following vulnerability has been resolved:
net: lan966x: Fix potential null-ptr-deref in lan966x_stats_init()
lan966x_stats_init() calls create_singlethread_workqueue() and not
checked the ret value, which may return NULL. And a null-ptr-deref may
happen:
lan966x_stats_init()
create_singlethread_workqueue() # failed, lan966x->stats_queue is NULL
queue_delayed_work()
queue_delayed_work_on()
__queue_delayed_work() # warning here, but continue
__queue_work() # access wq->flags, null-ptr-deref
Check the ret value and return -ENOMEM if it is NULL.
