PS4 update 5.03 Released
PS4 Firmware 5.03 was just released by Sony.
What does PS4 5.03 Do?
There is no official changelog yet as to what firmware 5.03 does. At the time of writing, the official Sony page still mentions 5.01 as the latest firmware.
However hacker SpecterDev, publicly the dev who has made the most progress on an actual implementation of the 4.05 exploit, has been hitting a few setbacks. Allegedly, he recently mentioned on Discord that he has the jailbreak working, but that launching any game after the exploit crashes the console (while running Linux is apparently ok). Last time I informally talked with him about the 4.05 exploit, he was still working on it.
There were rumored leaks of PS4 5.0x critical vulnerabilities as well, and it could be what firmware 5.03 patches, assuming important things were actually leaked and provided to Sony. As always, we’ll need to stay tuned for some statement from PS4 hackers to understand what this firmware changes.
Nevertheless, it’s unlikely that the 5.03 firmware patches any of the “known” undisclosed exploits. But as always, if you’re waiting for your console to be hacked, you should stay on as low a firmware as possible.
