  "title": "Input: lkkbd - disable pending work before freeing device",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  Input: lkkbd - disable pending work before freeing device  lkkbd_interrupt() schedules lk-\u003Etq via schedule_work(), and the work handler lkkbd_reinit() dereferences the lkkbd structure and its serio/input_dev fields.  lkkbd_disconnect() and error paths in lkkbd_connect() free the lkkbd structure without preventing the reinit work from being queued again until serio_close() returns. This can allow the work handler to run after the structure has been freed, leading to a potential use-after-free.  Use disable_work_sync() instead of cancel_work_sync() to ensure the reinit work cannot be re-queued, and call it both in lkkbd_disconnect() and in lkkbd_connect() error paths after serio_open().",
