## Overview

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

ALSA: hda: cs35l41: Fix NULL pointer dereference in cs35l41_hda_read_acpi()

The acpi_get_first_physical_node() function can return NULL, in which
case the get_device() function also returns NULL, but this value is
then dereferenced without checking,so add a check to prevent a crash.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

## Remediation

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