## Overview

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

ASoC: Intel: avs: Disable periods-elapsed work when closing PCM

avs_dai_fe_shutdown() handles the shutdown procedure for HOST HDAudio
stream while period-elapsed work services its IRQs. As the former
frees the DAI's private context, these two operations shall be
synchronized to avoid slab-use-after-free or worse errors.

## Remediation
