## Overview

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

firmware: arm_scmi: Fix OOB in scmi_power_name_get()

scmi_power_name_get() does not validate the domain number passed by the
external caller, which may lead to an out-of-bounds access.

Fix this by returning "unknown" for invalid domains, like
scmi_reset_name_get() does.

## Remediation

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