A Step Closer To A PlayStation 5 Jailbreak
30% Of The Time It Works All The Time
SpecterDev is an exploit developer who is fairly well known by those interested in console hacking, and they have proven once again that they deserve that reputation. They have released a jailbreak exploit that will work on some PlayStation 5’s at least some of the time. The exploit is somewhat limited, as you cannot run arbitrary code as of yet, however you may be able to gain root privileges and read/write access to large chunks of system memory. That is a big step towards developing a more robust exploit.
The jailbreak only works on PlayStation 5’s which are running the 4.3 firmware update, and should work on 4.5 with a bit of tweaking. Sony have since patched the issue and it is unlikely to work on newer firmware versions, which is up to 5.5 at the moment. The exploit sets up a race condition that exposes socket header memory before it is fully locked and uses that as a hook to start reading and writing data to the console.

While this exploit currently works on version 4.3 of the PS5 firmware (released last October), SpecterDev speculates that some slight changes could get a similar exploit to work on firmware version 4.5 (released last December).
