Summary
In the Linux kernel, the following vulnerability has been resolved: HID: nintendo: fix rumble worker null pointer deref We can dereference a null pointer trying to queue work to a destroyed workqueue. If the device is disconnected, nintendo_hid_remove is called, in which the rumble_queue is destroyed. Avoid using that queue to defer rumble work once the controller state is set to JOYCON_CTLR_STATE_REMOVED. This eliminates the null pointer dereference.

Podemos desreferenciar un puntero nulo que intenta poner en cola trabajo a una cola de trabajo destruida.

Evite usar esa cola para aplazar el trabajo de rumble una vez que el estado del mando se establezca en JOYCON_CTLR_STATE_REMOVED. Esto elimina la desreferencia del puntero nulo."
