Expected PS4 firmware 6.20 kernel exploit now in doubt
Back in March, we published a piece that brought hope to many. Popular developer @theflow0 announced that he had discovered a new vulnerability in the PlayStation 4 that could potentially result in a kernel exploit for consoles at or below firmware 6.20. Three months later, doubts are starting to creep in.
@theflow0 has now revealed that a vulnerability he discovered has been blocked off by Sony. That vulnerability would have allowed him to create a dongle jailbreak for the console, but that is apparently not to be.
The whole thing remains a bit uncertain, we must say. For one, the announcement makes no direct references to the previously teased firmware 6.20 exploit. There's also a chance this vulnerability is entirely different from the one discovered back in March. Possible, but improbable. Public opinion at the moment seems to be that any plans for a firmware 6.20 kernel exploit are now dead in the water.
In any case, the PlayStation 5 is right around the corner, and with the spotlight off the PlayStation 4, we wouldn't be surprised if other exploits and hacks started popping up in the near future.
We'll be sure to keep you updated on this.
Unfortunately Sony implemented their own HID descriptor parser on the PS4 which is not vulnerable. Otherwise I could have realized a dongle jailbreak :(— Andy Nguyen (@theflow0) June 5, 2020
