New kernel exploit for PS4s on 4.06 and 4.07, potential for 4.55, and userland exploit for 5.05
Well-known PS4 scene hacker "qwertyoruiop" has put out something new for the PlayStation 4; some code that will allow for a kernel exploit on up to 4.55 firmware. However, at this time, the userland exploit that goes with it only allows for users with 4.06 and 4.07 firmware to take advantage of it. Once a userland exploit exists for 4.55, however, then it will work, theoretically. For the first time, though, 4.06 and 4.07 firmware users can take part in using this exploit.
Additionally, a 5.01 webkit exploit was put on Github a few hours after qwertyoruiop's release. This one, made by AlexZzZ, is a proof of concept that could potentially lead to usermode access on lower 5.0x firmware. 5.05 compatibility has been tested by the community, and works as well. This is not the same as a kernel exploit, however, and won't have much potential for homebrew and backup related matters until a kernel exploit is found for 5.0.x. Nonetheless, the PS4 scene is making good progress, with quite a lot of new happenings in the past day.
Those that are still on 4.05 firmware should still stay put, until notified otherwise, as it's still the optimal firmware to be at. As always, be cautious when running homebrew and exploits on your system.
