Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> rapidio: fix possible name leaks when rio_add_device() fails<br /> <br /> Patch series "rapidio: fix three possible memory leaks".<br /> <br /> This patchset fixes three name leaks in error handling.<br /> - patch #1 fixes two name leaks while rio_add_device() fails.<br /> - patch #2 fixes a name leak while rio_register_mport() fails.<br /> <br /> <br /> This patch (of 2):<br /> <br /> If rio_add_device() returns error, the name allocated by dev_set_name()<br /> need be freed. It should use put_device() to give up the reference in the<br /> error path, so that the name can be freed in kobject_cleanup(), and the<br /> &amp;#39;rdev&amp;#39; can be freed in rio_release_dev().
