The\npcm_urb.packets[] is gone, as it's allocated by usb_alloc_urb(), hence\nit's found in urb.iso_frame_desc[] instead.\n\nThe conversions are rather straightforward; each embedded struct urb\nis changed to a pointer, and its callers are updated accordingly.\nThe resource for those structs are released in the common destructor\nfunctions (usb6fire_comm_free(), etc), which are called at both the\ninit error path and the disconnect.\n\nNo functional changes, only compile-tested.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
