CVE-2014-0196Linux kernel — a race in the terminal write path

The terminal write path in Linux kernels up to 3.14.3 mismanages driver access in one echo mode, so a race between long reads and writes corrupts memory. A local user gets a crash, or privileges.

YOUR NEXT MOVE

Update the kernel to your distribution's fixed build. A system still on a 3.x kernel from that era has collected a great deal more than this one flaw.
