PS5/PS4 “Lapse” Kernel exploit released, compatible up to PS4 12.02 and PS5 10.01 (but…)

Dropping a bomb on the scene, developer abc has released the “Lapse” Kernel exploit for PS4 and PS5 yesterday. The exploit is compatible up to Firmwares 12.02 for the PS4 and 10.01 for the PS5 (or, more specifically, the developer states it was patched in PS4 12.50 and PS5 10.20), so this is a massive release.

PS4/PS5 Lapse exploit details

The exploit relies on a double free vulnerability in aio_multi_delete, as described here. (Additional details on the PS4 Dev Wiki)

However, the currently released implementation is specifically for PS4 Firmwares 8.0x only at the moment. The exploit will need to be ported to other firmwares (something that is generally considered more difficult on the PS5), and, notably for recent firmwares and in particular on the PS5, we will need usermode entry points (webkit exploits, etc…).

In other words, implementing a fully working Jailbreak on higher firmwares (PS4 and PS5) could take some time. To my knowledge, there isn’t currently a public usermode exploit on those higher firmwares to act as an entry point (at this point I’m discounting the LUA exploits: you either got the games in time or you didn’t, and I don’t consider it practical. This is just my opinion of course)

PS5 Hypervisor Hack for 3.xx/4.xx ?

In parallel, and equally as interesting, Zecoxao has hinted that we might be getting a Hypervisor exploit for PS5 3.xx/4.xx. This would be a massive breakthrough, considering the PS5 Hypervisor moved outside of the Kernel, for increased security, with Firmwares 3.xx. A hypervisor exploit allows for basically full control of the system. It is considered “better” than realtime debugging/hack kstuff, from a performance and feature perspective.

hypervisor on 3.xx and 4.xx may be a reality soon enough

Keep in mind that this is currently only for PS4 8.0x, and that for the PS5, as well as higher PS4 Firmwares, the scene is technically waiting for new usermode entrypoints.
