CVE-2026-98066

/// Technical description

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

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
