What to do

AI-suggested

A patch has been applied to the Linux kernel that clears USB device pointers upon Type-C partner unregistration. Users should update to the fixed kernel version once available to ensure this vulnerability is remediated.

Description

A vulnerability in the Linux kernel's USB Type-C class handling could lead to the use of invalid USB device pointers after a Type-C partner disconnects. The issue is addressed by clearing these pointers upon partner unregistration to maintain a clean state for future connections.
