CVE-2026-31760

Estado: AnalizadaMedia (5.5)—

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.
