  3. CVE-2022-49805
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: lan966x: Se corrige un posible error de referencia nulo (PTR) en lan966x_stats_init(). Lan966x_stats_init() llama a create_singlethread_workqueue() y no verifica el valor ret, lo que puede devolver NULL. Podría ocurrir un error de referencia nulo (PTR): lan966x_stats_init() create_singlethread_workqueue() # Falló, lan966x->stats_queue es NULL. queue_delayed_work() queue_delayed_work_on(). __queue_delayed_work() # Advertencia, pero continúe. __queue_work() # Acceso a wq->flags, PTR-deref nulo. Verifique el valor ret y devuelva -ENOMEM si es NULL.
