  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: usb: 6fire: Avoid embedded URBs\n\nThe USB 6fire driver uses URBs embedded in different structs for PCM,\nMIDI and communication, and this is basically a buggy implementation\nnowadays; since a URB is managed with a refcount, this may lead to a\nUAF when the URB is released asynchronously.\n\nFor addressing the problem, this patch converts those embedded URBs to\nones that are properly allocated via usb_alloc_urb().  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.",
