In the Linux kernel, the following vulnerability has been resolved:
usbnet:fix NPE during rx_complete
Missing usbnetgoingaway Check in Critical Path. The usbsubmiturb function lacks a usbnetgoingaway validation, whereas _usbnetqueue_skb includes this check.
This inconsistency creates a race condition where: A URB request may succeed, but the corresponding SKB data fails to be queued.
Subsequent processes: (e.g., rxcomplete → deferbh → _skbunlink(skb, list)) attempt to access skb->next, triggering a NULL pointer dereference (Kernel Panic).
