CVE-2022-49806
|
| Sažetak |
In the Linux kernel, the following vulnerability has been resolved:
net: microchip: sparx5: Fix potential null-ptr-deref in sparx_stats_init() and sparx5_start()
sparx_stats_init() calls create_singlethread_workqueue() and not
checked the ret value, which may return NULL. And a null-ptr-deref may
happen:
sparx_stats_init()
create_singlethread_workqueue() # failed, sparx5->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. So as
sparx5_start(). |
