Linux Kernel RapidIO Use After Free Vulnerability
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.
