## Overview

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

ASoC: fsl: fsl_audmix: Validate written enum values

fsl_audmix_put_mix_clk_src() and fsl_audmix_put_out_src()
convert the user-provided enum item with snd_soc_enum_item_to_val()
before checking whether the item is within the enum's item count.

The generic snd_soc_put_enum_double() helper performs that
validation, but these callbacks use the converted value first: the
clock-source path tests it with BIT(), and the output-source path
indexes the prms transition table with it.

Reject out-of-range enum items before converting them.

## Remediation

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