This might be the biggest release on the PS4 scene in the past 2 years, and could be a game changer for a lot of people: following up on his promise, hacker TheFlow has released a PS4 kernel exploit for PS4 firmware 7.02 today.
To be clear the current PS4 firmware is 7.51. So, if you’re on the latest firmware, you’re out of luck. The exploit has been patched, as TheFlow worked in compliance with Sony’s bounty program to both ensure the PS4 remains secure AND allow the scene to benefit.
PS4 7.02 Jailbreak Wen? Soon!
However if you’ve managed to keep a PS4 on firmware 7.02 or below, you just have to wait a bit more until a full Jailbreak is released. The Kernel exploit needs to be combined with a usermode entry point (e.g. a Webkit exploit), and I assume it’s only a matter of days before a Jailbreak is released for PS4 7.02.
A public Webkit exploit exists up to firmware 6.72, so it’s possible a Jailbreak for that firmware could come up sooner than 7.02.
TheFlow credits Kiwidog, flatz, and SpecterDev for help on the exploit. He also extends thanks to PlayStation for allowing full disclosure.
