#3I guess it makes sense that the vulns would be in Sony's new kernel code, and not in its FreeBSD ancestor.

#4?
I think you've been exploited.

#6How huge is this?
This is an old exploit that has been since patched by Sony in firmware 4.07 (the last section of the article shows the fix).
Re: The First PS4 Kernel Exploit: Adieu
#7Sony appears to have patched it from firmware 4.06 and up. The adieu in the title appears to refer to bidding a farewell to the exploit rather than a codename for it ;-)
Great and insightful write-up nonetheless!

#8Am I reading it correctly that it's possible to invoke syscalls from Javascript? That seems like a monumentaly bad idea...

No, that's just a library they made that uses a WebKit exploit to invoke a ROP chain to run syscalls.

#10It's interesting to see that this is a vulnerability caused by PS4 specific kernel modifications. I guess it's good news for FreeBSD users that PS4 jailbreaks do not imply vulnerabilities in FreeBSD.
Conversely, I'd imagine the PS4 jailbreak community is vigourously looking for privilege escalations in FreeBSD, but no results so far. I wonder if anyone familiar with it could shed some light on whether that's a correct way of looking at it.
