This driver must validate the availability of the HID output report and its size before it can write LED states via buzz_set_leds(). This stops a heap overflow that is possible if a device provides a malicious HID output report: [ 108.171280] usb 1-1: New USB device found, idVendor=054c, idProduct=0002 ...
