Webkit exploit confirmed to run on PS4

It is apparently based on this: WebKit CVE-2012-3748 (<a href="http://www.securityfocus.com/bid/56362" rel="nofollow">http:&#x2F;&#x2F;www.securityfocus.com&#x2F;bid&#x2F;56362</a>)

Is this remotely exploitable in a dangerous way? Or just a tool for people to hack their own PS4s?
