ModChat 070 - Another PS4 Kernel Exploit for 7.55?

TheFloW returns yet again with a second PS4 related disclosure through HackerOne, this time being a limited disclosure as opposed to a full disclosure. Although details are a bit scarce this time around, I explain why I believe with an educated guess this disclosed kernel exploit looks to be present up to firmware 7.55! We also briefly discuss a new permanent UART solution released for the PS4, something awesome for developers and debuggers with jailbroken PS4 consoles!
