In the Linux kernel, the following vulnerability has been resolved:
net: usb: smsc75xx: Limit packet length to skb->len
Packet length retrieved from skb data may be larger than
the actual socket buffer length (up to 9026 bytes). In such
case the cloned skb passed up the network stack will leak
kernel memory contents.
