In the Linux kernel, the following vulnerability has been resolved:

net: usb: lan78xx: Limit packet length to skb->len

Packet length retrieved from descriptor may be larger than
the actual socket buffer length. In such case the cloned
skb passed up the network stack will leak kernel memory contents.

Additionally prevent integer underflow when size is less than
ETH_FCS_LEN.
