World-writable memory on Samsung Android phones

Here's a report on the xda-developers site stating that Samsung Android phones have an interesting feature added to the kernel: a /dev/exynos-mem device, world-writable, that gives access to all physical memory on the handset. "The good news is we can easily obtain root on these devices and the bad is there is no control over it." Owners of such phones might want to be especially careful about which software they install for a little while.
