## Overview

A flaw was found in the Linux kernel's sr9700 USB Ethernet driver. When processing incoming packets, the driver fails to properly account for packet header overhead during buffer length validation. An attacker capable of sending crafted packet data could trigger an out-of-bounds read, leading to a Denial of Service (DoS) via a system crash.
