## Overview

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

remoteproc: qcom_q6v5_adsp: Fix reference leak for device node

When calling of_parse_phandle_with_args(), the caller is responsible
to call of_node_put() to release the reference of device node.
In adsp_map_carveout, it does not release the reference.

## Remediation

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