Hacker kR105 has put a functional dlclose exploit online, making it possible to use custom code on a PlayStation 4 with firmware 1.76. He also put the necessary files online to run Linux on the console.

The exploit was already known, but appeared to be very unstable. In the latest version seems to have been resolved and kR105s version of the exploit is also a working root sandbox escape and jailbreak. However, the fact remains that it works only on PlayStation 4 with firmware 1.76 or older. In newer versions of the exploit is in fact no longer possible.

Furthermore, the hacker provides an update for the PlayStation 4 Playground software that makes it possible for people to start Linux without them there myself for a loader to write. For this, a user has a USB stick with a number of files necessary released on Github available are. KR105 also provides a distro of Linux for the PlayStation 4, so that interested parties do not themselves need to put together a release.

The exploit used to Linux on the console to run is probably the same exploits that have already used the hacker group fail0verflow in January this year at the Chaos Computer Conference. The group showed that a working Linux kernel on the PlayStation 4, and also gave their PS4 fork of the Linux kernel free. This made it not immediately possible for people to run Linux on a PS4 because the hackers were not known which exploits they used.
