PS5 Firmware 5.02 & PS4 Firmware 9.51 released, in context of FreeBSD heap buffer overflow vulnerability. Do not update
PlayStation pushed PS5 Firmware 22.01-05.02.00 (PS5 5.02) and PS4 Firmware 9.51 yesterday. Those are your typical “improves system performance” updates, but as always, we (and several prominent members of the hacking scene) recommend you do not update your console, if you can, and if you’re expecting to Jailbreak it eventually.
PS5 firmware 5.02 & PS4 Firmware 9.51 – What’s new
PS5 – 22.01-05.02.00
- This system software update improves system performance.
PS4 – 9.51
- This system software update improves system performance
Call me paranoid, but in the context of a $20’000 bounty awarded to TheFloW recently, the fact that both consoles get an update at the same time, and a recently revealed FreeBSD heap overflow vulnerability (CVE-2022-23088), that might impact both PS4 and PS5, I feel this update could be a significant hint for the scene. And it looks like I’m not the only one:
9.51 has been released. maybe patches something important. do not update!

I have been looking at it a bit, IF ps4 is vulnerable it could lead to a 9.5x kernel exploit, though any number of means that can send the packets required during scan… For PS5, it’s still a lot more work.

PS4 Jailbreak 9.00 was found through a diff with firmware 9.03. It might make sense for hackers to look deeper into what 9.51 is bringing to the table, as it seems some of them have access to what’s necessary to decrypt the latest and greatest firmwares…
PS4 9.51 and PS5 5.02 – Should I update?
As always, if your goal is to jailbreak your console, you should simply not update. Not that we know for sure that 5.02 and 9.51 patch anything significant, but because the recent history of PlayStation hacking tells us so: people who keep their console up to date do not get the Jailbreaks.
In an ideal world, you would have 2 consoles: one that you keep on a low firmware for a Jailbreak (or buy a low firmware one if you can find one), and one that you keep up to date in order to play your current gen games and access PlayStation online services. I know it’s easier said than done, but that’s how things are.
