Sony Playstation 4 4.05 FW Local Kernel Loader

In this project you will find a full implementation of the “namedobj” kernel exploit for the PlayStation 4 on 4.05. It will allow you to run arbitrary code as kernel in order to allow jailbreaking and kernel-level modifications to the system. This release does not contain any code related to defeating anti-piracy mechanisms or running homebrew. This exploit does include a loader that listens for payloads on port 9020 and will execute them.
