In the Linux kernel, the following vulnerability has been resolved: usbnet:fix NPE during rxcomplete Missing usbnetgoingaway Check in Critical Path. The usbsubmiturb function lacks a usbnetgoingaway validation, whereas _usbnetqueueskb 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).
