CVE-2026-80770

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.
