How to fix?

Upgrade torvalds/linux to version 4.8.1 or higher.

Overview

Affected versions of this package are vulnerable to NULL Pointer Dereference. The tower_probe function in drivers/usb/misc/legousbtower.c in the Linux kernel before 4.8.1 allows local users (who are physically proximate for inserting a crafted USB device) to gain privileges by leveraging a write-what-where condition that occurs after a race condition and a NULL pointer dereference.
