Problem Description:
If the push/pop level of the USB HID state is not restored within
the processing of the same HID item, an invalid memory location may be
used for subsequent HID item processing.
Impact:
An attacker with physical access to a USB port may be able to use a
specially crafted USB device to gain kernel or user-space code execution.
