PlayStation Hacker Sleirsgoevy has a pushed some Work-In-progress for the IPV6 PS5 Kernel exploit to his bd-jb repository. Emphasis on “work in progress”.

PS5 IPV6 Kernel exploit – TL, DR

Here’s what we know so far if you’re just joining us:

• Hacker TheFlow disclosed a Kernel exploit for the PS5 earlier this month, leveraging 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, specifically the bd-jb exploit
  • The bd-jb exploit requires a physical blu-ray drive, and therefore only works on PS5 physical edition. It’s possible an other usermode exploit (e.g. this webkit exploit) could be used in combination with the kernel exploit, for people on PS5 digital edition.
• It’s unclear at the moment which firmwares can technically be hacked (a given firmware must be vulnerable both to the usermode exploit being used – bd-jb or webkit – AND to the kernel exploit), but consensus seems to be that 4.03 is a given, 4.50 is likely.
• 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.

PS5 Homebrew still far away

It’s important at this point to mention that Sleirsgoevy’s commit is ongoing work, and most likely this doesn’t do anything significant at the moment.

As we’ve mentioned a few days ago, multiple hackers have stated that a PS5 Kernel exploit is not necessarily the holy grail, with lots of additional security measures in place on Sony’s latest console. If, and when something is ready, it will not be a full-fledged jailbreak for PS5, rather a barebones homebrew sandbox for hackers to dig further.

Multiple hackers are working on trying to piece together this PS5 Kernel exploit with the bd-jb usermode entrypoint. For people who don’t have a physical edition PS5, there’s also hope that eventually, this kernel exploit could be adapted to the webkit vulnerability that impacts both physical and digital editions of the PS5.
