World-writable memory on Samsung Android phones

My first thought was: after you get root, the next thing you do is "chmod 700 /dev/exynos-mem", but reading further, it seems lots of essential functionality is linked to a shared library that depends on read/write access (via memory map). Without access to the device, I don't know how many of those are running as root already.

I knew I'd seen this before: http://memegenerator.net/instance/24372872
