There doesn't appear to be much info about this other than it's a Linux 'kexec-like' from a webkit bug that apparently triggers a kernel exploit.

Awesome job!

Actually, I was expecting more technical stuff relating to how they jailbreak the system. PoC is also good though.

Typo in title (also present on YouTube).

Their name is fail0verflow.

Some of this has been covered in other blogs: https://cturt.github.io/ps4.html

"Hint: the NOP thing has nothing to do with exploits and everything to do with https://github.com/torvalds/linux/commit/0e16e4cfde70e1cf00f... "

So maybe the GPU firmware doesn't support the new packet?

I don't have any idea what I'm talking about, but it is mostly PC-like architecture with mostly FreeBSD running on it, right? Nothing really interesting, unlike it was with Cell processor.

They are not even subsidizing the hardware anymore, as I understand it, they sell it for about the same it costs to produce.

It's more impressive as a demonstration of owning the platform than getting Linux to run on something odd/unusual. The PS4 was only recently jailbroken.

Excellent demo. Furthermore, this scene in particular (at the 3 min 45 second mark) really brings home the achievement: https://www.youtube.com/watch?v=2A7V3GLWF6U&t=225

Looking at some component prices, you could probably assemble a passable gaming PC for under $350, so at $300 for a PS4 it does seem likely that Sony isn't losing money on console sales.
