  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: btsdio: fix use after free bug in btsdio_remove due to race condition\n\nIn btsdio_probe, the data->work is bound with btsdio_work. It will be\nstarted in btsdio_send_frame.\n\nIf the btsdio_remove runs with a unfinished work, there may be a race\ncondition that hdev is freed but used in btsdio_work. Fix it by\ncanceling the work before do cleanup in btsdio_remove.",
