## Overview

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

ASoC: Intel: avs: Do not share the name pointer between components

By sharing 'name' directly, tearing down components may lead to
use-after-free errors. Duplicate the name to avoid that.

At the same time, update the order of operations - since commit
cee28113db17 ("ASoC: dmaengine_pcm: Allow passing component name via
config") the framework does not override component->name if set before
invoking the initializer.

## Remediation

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