GHSA-M4V8-QP6H-HH9W
Vulnerability from github – Published: 2026-09-25 12:31 – Updated: 2026-09-25 12:31In 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.
