Subject: CVE-2024-50007: ALSA: asihpi: Fix potential OOB array access

Description
===========

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

ALSA: asihpi: Fix potential OOB array access

ASIHPI driver stores some values in the static array upon a response
from the driver, and its index depends on the firmware.  We shouldn't
trust it blindly.

This patch adds a sanity check of the array index to fit in the array
size.

The Linux kernel CVE team has assigned CVE-2024-50007 to this issue.

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
