Description OSIDB Bzimport 2025-05-02 16:01:41 UTC 
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.
