Description

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.
