This is just a rumor making rounds on the net at this point, but h3ck34 has been tweeting recently that a PS4 jailbreak device called the USB Whistle will be coming on February 20th with a PS4 CFW arriving no later than a month later on March 20th.

Is it legitimate? According to Wololo: "There are growing rumors that a group affiliated with the Cobra team (a team popular for some of their PS3 hardware mods, and the same team that announced the – yet to be released – cobra blackfin for PS Vita) have been working on a PS4 Jailbreak usb dongle."

While it wouldn't surprise me if the Cobra PS3 scene profiteers started milking the PS4 scene dry instead of releasing open-source freeware, I'm not holding my breath on this rumor being true just yet.

Below are some related tweets, feel free to comment with your own thoughts on the USB Whistle rumor:

Following the recent PS4 3.11 Out of Bound Read (Freetype 64bit Exploit), fail0verflow's PS4 patches and drivers and his previous PlayStation 4 Kernel Exploitation, today PS4 developers CTurt and Qwertyoruiop revealed news of a PS4 kernel heap overflow exploit alongside an analysis of sys_dynlib_prepare_dlclose for PlayStation 4 developers to examine further.

Below are some recent Tweets on their latest PS4 kernel exploit, as follows:

Finally, from Wololo comes a summary of their findings thus far with it, to quote:

• The exploit has been patched around firmware 2.00, so it will not be useful for people expecting a PS4 hack on the latest firmware 3.15.
• Cturt also announced that he will not release a fully weaponized exploit, and is just sharing the knowledge on how the vulnerability was exploited.
• He’s apparently actively working on the PS4 with other hackers such as Qwertyoruiop (a well know hacker famous for his work on iOS, among other things).
• The exploit itself lies in function sys_dynlib_prepare_dlclose and some of its internal calls such as copyin. Full details can be found in CTurt's article.
