CVE-2022-50245
Description
In the Linux kernel, the following vulnerability has been resolved:
rapidio: fix possible UAF when kfifo_alloc() fails
If kfifo_alloc() fails in mport_cdev_open(), goto err_fifo and just free priv. But priv is still in the chdev->file_list, then list traversal may cause UAF. This fixes the following smatch warning:
drivers/rapidio/devices/rio_mport_cdev.c:1930 mport_cdev_open() warn: '&priv->list' not removed from list
