Remediation
Red Hat statement
This flaw requires a Conexant CX24116 series TV-media card to be in the system for this driver to load. This flaw is when an attacker attempts to use the card to communicate with a satellite tv control subsystem ( via Digital Satellite Equipment Control command) by issuing a specially crafted ioctl to the device.
