In the Linux kernel, the following vulnerability has been resolved:
net: lan966x: Fix potential null-ptr-deref in lan966xstatsinit()
lan966xstatsinit() calls createsinglethreadworkqueue() and not checked the ret value, which may return NULL. And a null-ptr-deref may happen:
lan966xstatsinit() createsinglethreadworkqueue() # failed, lan966x->statsqueue is NULL queuedelayedwork() queuedelayedworkon() __queuedelayedwork() # warning here, but continue _queuework() # access wq->flags, null-ptr-deref
Check the ret value and return -ENOMEM if it is NULL.
