But it could still be dereferenced in the worker\nthread. The reason is that del_timer() will return directly\nregardless of whether the timer handler is running or not and\nthe worker could be rescheduled in the timer handler. As a result,\nthe UAF bug will happen. The racy situation is shown below:\n\n      (Thread 1)                 |      (Thread 2)\nsnd_aicapcm_pcm_close()          |\n ...                             |  run_spu_dma() //worker\n                                 |    mod_timer()\n  flush_work()                   |\n  del_timer()                    |  aica_period_elapsed() //timer\n  kfree(dreamcastcard-\u003echannel)  |    schedule_work()\n                                 |  run_spu_dma() //worker\n  ...                            |    dreamcastcard-\u003echannel-\u003e //USE\n\nIn order to mitigate this bug and other possible corner cases,\ncall mod_timer() conditionally in run_spu_dma(), then implement\nPCM sync_stop op to cancel both the timer and worker.
