There's been no shortage of developments in the PS4 jailbreak community over the last day or so; we reported on a kernel exploit earlier today, in fact. And now, there's another exciting development, hacker Qwertyoruiop (who you might remember from his direct contributions to the PS4 1.76 Jailbreak years ago) has shown that he has cracked open PS4 firmware 5.00 via a new entry point in the firmware. The new firmware version, which was released only a few weeks ago, was already rumored to have the same kernel vulnerabilities as its predecessor, and it seems their exploitation viability is already been realized.

The screenshot presents what appears to be usermode access to the firmware via a webkit vulnerability, which wouldn't be very exploitable. However, it seems that the kernel exploit in firmware version 4.55 is still present and open to exploitation, leaving plenty of potential for further development of jailbreak tools for the PS4. Additionally, Qwertyuiop stated he "already has a [kernel] bug, and just needs to exploit it", as can be seen in the tweet below.
not yet, but i already have the bug, just need to exploit it

Given the recent developments in hacking the PS4 and the exploration of the possibility of running native homebrew applications on both existing jailbroken firmware and newer firmware, it seems we are inching closer and closer to a full jailbreak for the latest PS4 firmware. And if anyone could pull it off, we'd put our money on Qwertyuiop. All things considered, it seems like the PS4 jailbreaking community might not be on life support anymore.
What do you guys think of these developments? Do you think they'll lead to a full jailbreak and native homebrew development for the PS4, or will they be fruitless like other previous attempts? Let us know what you think in the comments, or post over on our forums with your thoughts.
