## Overview

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

ALSA: asihpi: Fix potential OOB array access at reading cache

find_control() to retrieve a cached info accesses the array with the
given index blindly, which may lead to an OOB array access.
Add a sanity check for avoiding it.
