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

Description A device leak exists in the rtw88 wifi driver. The driver takes a reference to the USB device during the probe process but fails to release it when certain probe errors occur, such as descriptor parsing failures. This happens because the driver core already maintains a reference to the USB interface and its parent USB device while the interface is bound to a driver, making the additional reference redundant.

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