Developer and hacker SpecterDev released a fully-functional much-awaited kernel exploit for PlayStation 4 (firmware 4.05). Now available on Github,  the kernel exploit for the PlayStation 4 on 4.05FW allows users to run Linux on the gaming console and enables jailbreaking and kernel-level modifications to the system. Jailbreaking allows users to run custom code on the console and install mods, third-party applications, and games that are typically not possible. “This exploit is actually incredibly stable at around 95% in my tests. WebKit very rarely crashes and the same is true with kernel. I’ve built in a patch so the kernel exploit will only run once on the system. You can still make additional patches via payloads,” said the the developer.
