One of the concerns related to the recent PS5 IPV6 exploit was that it could be leaving digital PS5 owners out in the cold. PlayStation hacker SpecterDev has put these concerns to ease, announcing he’s getting close to a full implementation that leverages the Webkit exploit (instead of bd-jb), which will be compatible with the PS5 digital edition, up to firmware 4.03 included.

PS5 IPV6 Kernel exploit – TL, DR

Here’s what we know so far if you’re just joining us (you can probably skip this part if you’ve been following this exploit since day 1):

• Hacker TheFlow disclosed a Kernel exploit for the PS5 in September, which leverages a vulnerability in PS5’s IPV6 implementation.
  • The exploit is the same as an exploit that was used to Jailbreak the PS4 in 2021
• Multiple hackers are trying to implement this exploit based on current knowledge. To do this hey have to 1) write a working implementation of the Kernel exploit and 2) piece it together with a usermode entry point, with several hackers focusing specifically on the bd-jb exploit
  • The bd-jb exploit requires a physical blu-ray drive, and therefore only works on PS5 physical edition. But it’s not the only entry point available! Other hackers are working on an implementation using this webkit exploit in particular for people on PS5 digital edition (or people who don’t want to burn blu-rays to run an exploit).
• PS5s up to Firmware 4.03 included can be hacked through the webkit + kernel exploit combination. It’s also believed that for Physical PS5s, up to 4.50 or 4.51 might be compatible though the bd-jb + kernel exploit combination.
• Hackers have been verbose that even when this is achieved, what we’ll get will most likely be a minimal homebrew environment, useful mostly for developers only.

SpecterDev working on Webkit + Kernel implementation

We’ve had access to a Webkit exploit on PS5 for a long time, and SpecterDev has been working on chaining it with the recently released IPV6 Kernel exploit. He’s stating he’s getting close to a release. We have to keep in mind that this is not going to be a “Jailbreak” as we’ve been accustomed to on the PS4, and that the end result might more likely be a barebones “run your own binaries to some extent” environment. We’ll have to wait and see.

For those interested in a webkit PS5 kernel exploit implementation, it’s on track to be ready soon – stay on 4.03 🙂

Still wanna do some cleanup and such but a lot of the major work is done. Obv without @theflow0 this wouldn’t be possible :P. 1/2 pic.twitter.com/rqSqJaVcXJ

In any case, this is good news for Digital Edition PS5 owners, who thought they might be left behind with a bd-jb based exploit.

SpecterDev credits a significant list of people involved in this work, namely Znullptr, Chendochap, sleirsgoevy, psxdev, flat_z, Zecoxao, Socraticbliss, and of course TheFloW. That’s an all-star rooster if I’ve ever seen one.

To summarize:

If you’re on PS5 Digital edition, you’ll have to be on firmware 4.03 or under to use this exploit (Webkit + Kernel)

If you’re on PS5 physical edition, the above works as well ( you will be able to use Webkit + Kernel if you’re on 4.03 or below), but alternatively you will be able to use bd-jb+kernel, possibly up to 4.51 included.
