n 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).

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usbnet:fix NPE durante rx_complete. Falta la comprobación usbnet_going_away en la ruta crítica. La función usb_submit_urb carece de la validación usbnet_going_away, mientras que __usbnet_queue_skb sí la incluye. Esta inconsistencia crea una condición de ejecución donde: una solicitud URB puede ser exitosa, pero los datos SKB correspondientes no se ponen en cola. Los procesos posteriores (p. ej., rx_complete ? defer_bh ? __skb_unlink(skb, list)) intentan acceder a skb->next, lo que provoca una desreferencia de puntero nulo (pánico del kernel).
