- Summary
- net: usb: lan78xx: Limit packet length to skb->len
- Details
-
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 ETHFCSLEN.
