CVE-2025-21934 Information

Description

In the Linux kernel the following vulnerability has been resolved:

rapidio: fix an API misues when rio_add_net() fails

rio_add_net() calls device_register() and fails when device_register() fails. Thus put_device() should be used rather than kfree(). Add \mport->net = NULL;\ to avoid a use after free issue.
