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.
