During the closed conference held in Seoul, South Korea, the Chaitlin team talked about its feat, very little information was filtered, but we managed to get a bit more.
The first information we could find is the famous slide from another angle and much more readable. The Zer0Con conference was held in front of security experts, with some members of Project Zero Google (the Zero-day vulnerability research team), but also some members of the Microsoft security team, Pwnzen of the team Pangu (jailbreak iOS) and, of course, Team Chaitin's Slipper.
The team member Chaitlin, Slipper, was finally able to confirm that during the GeekPwn 2016 held on October 24, 2016, during which they showed the launch of Linux on the firmware 4.01, they used the fault Firekaku.
Firekaku is a flaw derived from Henkaku, ported from PS Vita on PS4 as of firmware 3.15, 3.50 and 3.55 by https://github.com/Fire30/PS4-3.55-Code-Execution-PoC, the Chaitlin Team has only adapted it to firmware 4.01, much like what Specter does With the work of qwertyoruiopz when he released the supports of 3.50, 3.55, and 3.70.
Unfortunately, the exploit used behind the flaw was made public and handed over to Sony, and it was corrected by Sony from firmware 4.07. Moreover, Chailin signed a non-disclosure agreement on the kernel exploit used after the fault, Firekaku not being the exploit kernel, simply the entry point in user mode therefore rather limited, it is better to rely on The work of Luca Todesco (qwertyoruiop).
All this to say in the end, stay under the firmware under which you are currently ... we must forget Chaitlin who will never reveal the feat, we must look to the side of qwertyoruiop, Specter and the team Rebug.
Here is a slide rather rich and which transcribes well the current situation
