On December 26, Developer SpecterDev released a PS4 4.05 Kernel Exploit project on Github.
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, to allow jailbreaking and kernel-level modifications to the system. This release however, 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 upon receival.
PlayStation Jailbreak was the first Universal Serial Bus chipset that allows unauthorized code execution, such as homebrew, on the PlayStation 3. It bypasses a system security check using a memory exploit which occurs with USB devices that allow the execution of unsigned code. One of the most popular pieces of homebrew software used with the device is Backup Manager, which allows users to copy game titles from the optical media to the hard drive of the PlayStation 3. Backup Manager can also be used to run homebrew applications that are created to run in the console’s native mode. __Wiki
