PS4 Sasuke 4.50 Beta Webkit Crash Memory Overload Discovered

Hey guys, following my Shingen Beta 4.00 crash report and Sony's Sasuke Beta 4.50 update I found a webkit crash in the latest Beta 2 Firmware and thought I would ask if it works for you guys too.

Here is the link: http://www.filldisk.com/

It tries to fill the disk of the PS4 but instead crashes after about 2 min.

NOTE: It does work on 4.50

It will not cause code execution, it is just a note cause it is the first one I have seen for 4.50.

Update: I also found that TypedArray.fill can be used to exploit and crash PS4 Firmware 4.50 Beta for those who wish to host the html5 file on xampp.

Could someone upload video? and what can this lead to? I am eager for something actually useful.

They're documenting html / javascript code that crashes the PS4, nothing video-worthy since its from public browser exploit databases and doesn't get you out of the PS4 sandbox to do anything useful like running native unsigned code unfortunately.

Here's a quick recap from mete2221 and SilicaAndPina on various PlayStation 4 crashes (which can be reproduced by simply running PSNS: from the PS4's browser):
