| 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. |
