Any app has full memory access via /dev/exynos-mem<p>Largest security hole ever?

I currently have an S3 and this isn't the first serious exploit I've come across for it.<p>Does anyone have any suggestions for a serious secure phone? I don't need all the bells and whistles and don't install many apps. Mostly just email, text, and web browsing.

With so many Samsung Android phones (<a href="http://en.wikipedia.org/wiki/Comparison_of_Android_devices#Samsung" rel="nofollow">http://en.wikipedia.org/wiki/Comparison_of_Android_devices#S...</a>) flooding out to stay competitive and get a quick win over the iOS as well as other manufacturer's Android devices, it's obvious that some of their stuffs will eventually fall through the crack as result of poor QA. I will not be too surprised to see other brand Android phones have similar security issues.<p>I can almost see that Android is quickly becoming the next Windows 95.

Looks like on Samsung devices, every app has full r/w memory acess via /dev/exynos-mem<p>I wonder two things:<p>1) if this is Samsung only or if its an Android issue.<p>2) If and how this can bee used to become root. TFA says "The good news is we can easily obtain root on these devices" but doesnt say how.

Is anyone else finding that thread full of Google adverts for Samsung phones? It's rather funny.

How was this even posted? It's the exact same link as yesterday in addition to the other link about this yesterday.<p>Ah, I see the original has an anchor in the URL: <a href="http://news.ycombinator.com/item?id=4928277" rel="nofollow">http://news.ycombinator.com/item?id=4928277</a>

As an Android newbie -- how easy is it to get out kernel patches to [all these millions of users'] phones?<p>(No, I'm not a black hat -- I don't have a hat of <i>any</i> colour.)
