CVE-2022-49974 Information

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.
