CVE-2026-31760 Details
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.
A memory leak vulnerability has been identified in the Linux kernel's GPIB USB driver, specifically in versions prior to the patch. The issue arises because the driver retains references to USB devices of registered interfaces during the attachment process, without releasing them. This unaddressed retention leads to a memory leak when devices are disconnected.
Users can apply the patch available in the Linux kernel stable tree to address this vulnerability.
