net: usb: kaweth: validate USB endpoints
Description

In the Linux kernel, the following vulnerability has been resolved: net: usb: kaweth: validate USB endpoints The kaweth driver should validate that the device it is probing has the proper number and types of USB endpoints it is expecting before it binds to it. If a malicious device were to not have the same urbs the driver will crash later on when it blindly accesses these endpoints.
