Specifically, Sleirsgoevy has released a working implementation of the Blu-Ray exploit, which in theory should work for firmwares 9.03 and 9.04.ĭetails can be found here, but keep in mind that this is a usermode exploit. People on firmwares 9.03 and 9.04 have a dim ray of hope, with the BD-JB usermode exploit. Although that’s the way the game is played, what hope is there today for people running firmware 9.03 or above? Firmware 9.03/9.04 Anybody running a PS4 on firmware 9.00 or lower can enjoy the benefits of the Jailbreak today, but people on higher firmwares feel like they’ve been left in the cold. It’s been almost a year since the latest PS4 Jailbreak was released, for firmware 9.00. Hence, two exploits required for a Jailbreak: the “usermode” exploit, or the entry point, and the “kernel” exploit, or privilege escalation. That’s what usually known as a “kernel” exploit, because historically on consoles this gave us access to the firmware parts of the RAM, or the kernel. That initial entry point is typically referred to as a usermode exploit.įrom there, you need a “privilege escalation”, a way to get to a higher level of authorization into the machine’s more secure pieces of code. ![]() These inputs will trigger some bug in the application that’s running them (whether it’s webkit, a game, or something else) and give you some way to run code on the console. That “way” can be some malicious javascript on a web page, or a cleverly crafted save file for a specific game. That’s a bit of an oversimplification to be honest, but the idea is that you first need a way to run unsigned code by hijacking a running process on the console. ![]() As a reminder, and at the risk of sounding like a broken record, a PS4 Jailbreak basically requires two exploits.
