Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: usb: smsc95xx: Limitar la longitud del paquete a skb->len. La longitud del paquete obtenida del descriptor puede ser mayor que la longitud real del búfer del socket. En tal caso, el skb clonado que se pasa a la pila de red filtrará el contenido de la memoria del kernel.
