Following their work-in-progress, PlayStation 4 developer zecoxao with help from droogie1xp, psxdev, VVildCard777, fx0code, CTurt for the exploit and kr105 for the payload have achieved kernel and code execution despite the Grey Screen of Death (GSoD) and fully implemented the Dlclose Exploit for PS4 Firmware 1.01 now! :love:

Download: PS4-dlclose-master.zip / GIT / PS4 Playground 1.01 Demo

From the README.md file, to quote: PS4-dlclose 1.01 Version

Fully implemented dlclose exploit for PS4 fw 1.01. Compile it with CTurt's.

This is the bare working exploit, you must add your own payload code to make it do anything useful. Enjoy!

Here's to hoping this PlayStation 4 kernel exploit port leads PS4 homebrew developers to uncovering more vulnerabilities and even some unknown goodies perhaps! <3

Code:
*(uint16_t *)0xFFFFFFFF827E31EE = 0x9090;
*(uint16_t *)0xFFFFFFFF827E31FD = 0x9090;
*(uint16_t *)0xFFFFFFFF827E3202 = 0x9090;
Patches for decrypt_pup_header (1.76):
Code:
*(uint16_t *) 0xFFFFFFFF827C445C = 0x9090;
*(uint16_t *) 0xFFFFFFFF827C446B = 0x9090;
*(uint16_t *) 0xFFFFFFFF827C4470 = 0x9090;
Cheers to @CTurt, @kr105, @oneman123, @zecoxao and everyone idling in the PSXHAX Shoutbox this weekend! :beer:

Don't get me wrong I admire the work of these developers but instead of moving forward they're going backwards.

What's the point of this? If there are people still on 1.01 they could simply update to fw 1.78

So there is actually no need for that or am I missing something?

I finally get why they backtracked onto 1.01
So basically since that's the kind of early firmware it is sure to have a lot of bugs in it right?

But many keep asking why exploit that instead of latest FW. The answer is the bugs in that old FW might just might still be present in latest FW. Sony may not have patched all of those bugs.

So if the bug used to exploit 1.01 can be used to do the same on latest FW. Then God bless this scene. If not, there are a lot of undiscovered bugs that may just do the trick.
