## Description

In the Linux kernel, the following vulnerability has been resolved: gpib: lpvo_usb: fix memory leak on disconnect The driver iterates over the registered USB interfaces during GPIB attach and takes a reference to their USB devices until a match is found. These references are never released which leads to a memory leak when devices are disconnected. Fix the leak by dropping the unnecessary references.
