## Overview

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

ALSA: caiaq: Fix potential double-free at error path

The fix for caiaq driver's resource management to handle the errors
tries to release the resources in a common destructor call, but as a
sashiko review for another patch suggested, some of the audio
resources such as URBs have been already freed, and this may lead to a
double-free.

For addressing the double-free, call the common destructor function
from each place, and assure that the resource pointers get cleared.

## Remediation

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