Red Hat and security company Perception Point recently revealed a Linux flaw they say could affect servers, PCs and up to 66 percent of Android phones on the market. The vulnerability directly affects the OS's kernel, and could give attackers a way to gain code execution and take over a device, according to Perception Point. Google, however, fired back strongly at the claim, particularly because it wasn't given the usual window to address the flaw before it was publicly released. "Since this issue was released without prior notice to the Android Security Team, we are now investigating the claims ... [however,] we believe that the number of Android devices affected is significantly smaller than initially reported."
