Summary
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.
