Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak occurs in the lpvo usb driver within the GPIB subsystem. During the GPIB attach process, the driver iterates through registered USB interfaces and acquires references to USB devices until a match is found. These references are not released, resulting in a memory leak when devices are disconnected.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
