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.
