## Overview

In the Linux kernel, the following vulnerability has been resolved:

wifi: carl9170: add a proper sanity check for endpoints

Syzkaller reports [1] hitting a warning which is caused by presence
of a wrong endpoint type at the URB sumbitting stage. While there
was a check for a specific 4th endpoint, since it can switch types
between bulk and interrupt, other endpoints are trusted implicitly.
Similar warning is triggered in a couple of other syzbot issues [2].

Fix the issue by doing a comprehensive check of all endpoints
taking into account difference between high- and full-speed
configuration.
