Zack Whittaker, writing for ZDNet: As many as 80 percent of Android devices are vulnerable to a recently disclosed Linux kernel vulnerability. Security firm Lookout said in a blog post on Monday that the flaw affects all phones and tablets that are running Android 4.4 KitKat and later, which comes with the affected Linux kernel 3.6 or newer. According to recent statistics, the number of devices affected might run past 1.4 billion phones and tablets — including devices running the Android Nougat developer preview. Windows and Macs are not affected by the vulnerability. The flaw, disclosed at the Usenix security conference last week, is complicated and difficult to exploit. If an attacker can pull off an exploit, they could inject malicious code into unencrypted web traffic from “anywhere”.
