## Overview

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

thunderbolt: Keep XDomain reference during the lifetime of a service

This is needed because we release the service ID in tb_service_release()
and the ID array is owned by the parent XDomain.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
