    Developer @SpecterDev published a write-up on his GitHub repo about the latest PS4 Kernel Exploit on System Firmware 4.55. But as you may already recognized from the Title of this News, he explains at his write-up that this mentioned Kernel Exploit is not only convenient for the PS4 itself - it could be also useful for other console platforms using FreeBSD in general, which sounds very interesting. This great write-up also shows how the PS4's System Firmware is running on FreeBSD in general and how the Developers behind the PS4 (didn't) tried to made this System secured from exploiting it.

    • Welcome to the kernel portion of the PS4 4.55FW full exploit chain write-up. This bug was found by qwerty, and is fairly unique in the way it's exploited, so I wanted to do a detailed write-up on how it worked. The full source of the exploit can be found here. I've previously covered the webkit exploit implementation for userland access here.

      Note: While this bug is primarily interesting for exploitation on the PS4, this bug can also potentially be exploited on other unpatched platforms using FreeBSD if the attacker has read/write permissions on /dev/bpf, or if they want to escalate from root user to kernel code execution. As such, I've published it under the "FreeBSD" folder and not the "PS4" folder.


    The Full write-up is available here.
