## Overview

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

ASoC: meson: aiu: Validate written enum values

The AIU HDMI and internal codec mux put callbacks use the written enum
value with snd_soc_enum_item_to_val() before checking whether the value is
valid for the enumeration.

Reject out-of-range values before converting the enum item, matching the
validation already done by the G12A HDMI and internal codec mux controls.

## Remediation

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