CVE-2026-31604

MediumCVSS 5.5/10Last modified Nov 11, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

wifi: rtw88: fix device leak on probe failure

Driver core holds a reference to the USB interface and its parent USB device while the interface is bound to a driver and there is no need to take additional references unless the structures are needed after disconnect.

This driver takes a reference to the USB device during probe but does not to release it on all probe errors (e.g. when descriptor parsing fails).

Drop the redundant device reference to fix the leak, reduce cargo culting, make it easier to spot drivers where an extra reference is needed, and reduce the risk of further memory leaks.
