Description OSIDB Bzimport 2026-05-01 15:09:19 UTC 
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.
