In a series of tweets, Playstation 4 developer CTurt has said that the PS4 kernel exploit had been made to work, leading to the ability to dump system RAM and more.
PS4 kernel exploit finally working! Thanks to everyone involved!

Just broke WebKit process out of a FreeBSD jail (cred->cr_prison = &prison0). Guess you could say the PS4 is now officially “jailbroken” 😛 — CTurt (@CTurtE) December 12, 2015
This has a number of interesting implications. On one hand, this would allow running emulators for the PS2 and such, and possibly release FPS, FOV locks etc. On the other hand, the more obvious consequence is allowing games to be easily pirated and run. This might actually increase the sales of the PS4 system in markets such as India, but how it bodes for future development will be something to watch.
We’ll keep you updated on any developments as they come. Right now, there is no way to tell if this will lead to the rampant jailbreaking we saw in previous console generations.
