Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.8.1

Description The issue allows local users who are physically proximate for inserting a crafted USB device to gain privileges. This is achieved by leveraging a write-what-where condition that occurs after a race condition and a NULL pointer dereference in the tower probe function.

Recommendations For versions prior to 4.8.1, update to version 4.8.1 or later to resolve the issue. As a temporary workaround, consider restricting physical access to the system to prevent the insertion of crafted USB devices.
