Description

A flaw was found in the Linux kernel's kaweth driver. A malicious USB device can exploit this vulnerability by not providing the expected number and types of USB endpoints during device probing. The driver fails to validate these endpoints, leading to an attempt to blindly access them, which can cause the driver to crash. This results in a Denial of Service (DoS) for the affected system.
