Towelroot uses the Futex vuln disclosed June 2, 2014. There's been a running bet on who would be the first to roll this bug into a one-click root for Android
Edit: this looks like a pretty bad vulnerability for samsung owners (or all android devices with an unpatched kernel) - any app could silently root your phone?
