## Overview

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

ALSA: usb-audio: Stop parsing channels bits when all channels are found.

If a usb audio device sets more bits than the amount of channels
it could write outside of the map array.

## Affected

- `linux_kernel >= 3.8, < 4.19.311`
- `linux_kernel >= 4.20, < 5.4.273`
- `linux_kernel >= 5.5, < 5.10.214`
- `linux_kernel >= 5.11, < 5.15.153`
- `linux_kernel >= 5.16, < 6.1.83`
- `linux_kernel >= 6.2, < 6.6.23`
- `linux_kernel >= 6.7, < 6.7.11`
- `linux_kernel >= 6.8, < 6.8.2`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.2`
