Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
rapidio: fix possible UAF when kfifo_alloc() fails<br />
<br />
If kfifo_alloc() fails in mport_cdev_open(), goto err_fifo and just free<br />
priv. But priv is still in the chdev->file_list, then list traversal<br />
may cause UAF. This fixes the following smatch warning:<br />
<br />
drivers/rapidio/devices/rio_mport_cdev.c:1930 mport_cdev_open() warn: &#39;&priv->list&#39; not removed from list
