  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: us144mkii: capture_urb_complete: redundant usb_anchor_urb corrupts anchor list on each resubmission\n\nIn capture_urb_complete(), usb_anchor_urb() is called on every\ncompletion callback, but the URB is already anchored from the\ninitial submission in tascam_trigger_start(). Each redundant call\ncorrupts the anchor's doubly-linked list and inflates the URB\nrefcount. When usb_kill_anchored_urbs() traverses the list during\nstream stop / suspend / disconnect, the corrupted list leads to\nuse-after-free.\n\nRemove the redundant usb_anchor_urb() from the resubmit path.",
