Description

In the Linux kernel, the following vulnerability has been resolved:  parisc: led: Fix potential null-ptr-deref in start_task()  start_task() calls create_singlethread_workqueue() and not checked the ret value, which may return NULL. And a null-ptr-deref may happen:  start_task()     create_singlethread_workqueue() # failed, led_wq 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.
