for caiaq driver's resource management to handle the errors\ntries to release the resources in a common destructor call, but as a\nsashiko review for another patch suggested, some of the audio\nresources such as URBs have been already freed, and this may lead to a\ndouble-free.\n\nFor addressing the double-free, call the common destructor function\nfrom each place, and assure that the resource pointers get cleared.","state":0,"publishedAt":"2026-09-25T10:24:08.999+00:00","modifiedAt":"2026-10-19T09:13:15.973+00:00","affected":[{"ecosystem":"Vendor
