What to do

AI-suggested

A patch has been applied to the Linux kernel to fix this deadlock by adding proper mutex locking logic in the UCSI displayport driver. Users should update to the fixed kernel version once available. No additional mitigation steps are indicated.

Description

A deadlock vulnerability in the Linux kernel's USB Type-C UCSI displayport driver was fixed by introducing mutex lock functions that prevent improper locking when no connection is established. This resolves a deadlock scenario involving the connector mutex and displayport alternate mode work.
