  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: nintendo: stop device IO before hid_hw_stop on probe failure\n\nnintendo_hid_probe() calls hid_device_io_start() before joycon_init()\nand joycon_leds_create().  If either fails, the error path jumps to\nerr_close which calls hid_hw_close()/hid_hw_stop() without first calling\nhid_device_io_stop().\n\nhid_hw_stop() does not stop device IO, so hid_input_report() may still\nrun and access driver data that is being torn down, resulting in a\nuse-after-free.\n\nAdd an err_io_stop label that calls hid_device_io_stop() before\nhid_hw_close(), and point the two post-io_start error paths at it.",
