"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: usx2y: us144mkii: fix work UAF on disconnect\n\ntascam_disconnect() cancels capture_work and midi_in_work before\nusb_kill_anchored_urbs() kills the capture/MIDI-in URBs. Those URBs\nself-resubmit, and their completion handlers reschedule the work.\n\nA URB that completes in the small window between cancel_work_sync() and\nusb_kill_anchored_urbs() therefore re-arms the work after its only\ncancel. Nothing cancels it again before snd_card_free() frees the\ncard-private tascam structure, so the work handler then runs on freed\nmemory.\n\nKill the anchored URBs before cancelling the work; once the work is\ncancelled no remaining URB can complete to re-arm it."
