CVE-2025-22050

MediumCVSS 4.7/10Last modified Nov 5, 2026

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).
