HID: nintendo: stop device IO before hid_hw_stop on probe failure

Assigner: Linux
Reserved: 26.08.2026 Published: 04.09.2026 Updated: 04.09.2026

In the Linux kernel, the following vulnerability has been resolved:

HID: nintendo: stop device IO before hid_hw_stop on probe failure

nintendo_hid_probe() calls hid_device_io_start() before joycon_init() and joycon_leds_create(). If either fails, the error path jumps to err_close which calls hid_hw_close()/hid_hw_stop() without first calling hid_device_io_stop().

hid_hw_stop() does not stop device IO, so hid_input_report() may still run and access driver data that is being torn down, resulting in a use-after-free.

Add an err_io_stop label that calls hid_device_io_stop() before hid_hw_close(), and point the two post-io_start error paths at it.
