## Overview

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

thunderbolt: Release request if tb_cfg_request() fails in __tb_xdomain_response()

If tb_cfg_request() fails setting up the request (for example the
control channel is shut down already) it returns an error without
calling the callback. To avoid leaking that memory, call
tb_cfg_request_put() if tb_cfg_request() fails.

## Remediation

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