Sony released firmware update 5.01 yesterday. According to the eu playstation site, the update is optional (meaning you can still access PSN online services if you stay on 5.00 for now). As often with these minor updates, the changelog is as generic and cryptic as possible, only stating that this update “improves system performance”.
This is slightly different from the other “improves system stability” message, which usually hints at patched vulnerabilities.
What does PS4 5.01 Do?
Mainstream gaming sites usually provide information on improvements brought to a specific game, but this doesn’t seem to be the case this time. Most of them have instead chosen to re-state what the recent 5.00 firmware brought to the table.
I’ve however seen a handful of mainstream technology sites claiming that this update patches Qwertuyoruiop’s 5.00 kernel exploit, and some scene websites hinting that this might patch flat_z’s recent technique to install unsigned packages on jailbroken PS4 consoles. But there’s actually no evidence of any of these being patched, as no hacker has come out yet to describe what this update does to their private exploits.
It’s actually very unlikely that this 5.01 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.
