CVE-2025-22050 Information

Description

In the Linux kernel the following vulnerability has been resolved:

usbnet:fix NPE during rx_complete

Missing usbnet_going_away Check in Critical Path. The usb_submit_urb function lacks a usbnet_going_away validation whereas __usbnet_queue_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. rx_complete ? defer_bh ? __skb_unlink(skb list)) attempt to access skb->next triggering a NULL pointer dereference (Kernel Panic).
