ALSA: us144mkii: capture_urb_complete: redundant usb_anchor_urb corrupts anchor list on each resubmission<\/p>\n
In 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.<\/p>\n
