Here, qwertyoruiopz comes to the moment to confirm that it has a feat webkit on firmware 4.50 and 4.55 and especially that that allows it to have access to LPE kernel.
As we can see from his proof of concept, he realizes thanks to the exploit webkit a launch of several courses on the kernel, he had already had access to the writing and reading of the kernel and there it seems that the progress Realized are important and especially it works on the firmware 4.50 and 4.55!
In the first stage, we see a step of searching for parameters to be able to read and write, the famous memory zone that Specter had explained to us, then loads the gadgets, caches them and launches them, and finally stage3 launches syscalls .
In short, thank you to wait, and yes hope makes live! A tip, unplug your console from your internet access because Sony will probably quickly release a new firmware ...
Do not update to 4.50 or 4.55, wait a bit there is no urgency especially as long as no PoC is available.
