Tested the exploit on CentOS:

Linux 2.6.32-358.6.1.el6.x86_64 #1 SMP Tue Apr 23 19:29:00 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux (latest CentOS kernel):

  [user@centos ~]$ gcc -O2 exploit.c 
  [user@centos ~]$ ./a.out

I tested on two Ubuntu systems:

* Linux beqbrgbrg1ux006.tpvision.com 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

* Linux DrinkCoffee 3.5.0-25-generic #38-Ubuntu SMP Mon Feb 18 23:27:42 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

And the process gets killed because of a kernel oops in both.

Kernel panic on Ubuntu 12.04

* Linux bk-ak 3.2.0-40-generic #64-Ubuntu SMP Mon Mar 25 21:22:10 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Same on Ubuntu 13.04 w/ 3.8.0-19-generic.

Tested on Arch Linux x64: [test@libros-dev tmp]$ uname -a Linux libros-dev 3.8.5-1-ARCH #1 SMP PREEMPT Fri Mar 29 19:18:14 CET 2013 x86_64 GNU/Linux

[test@libros-dev tmp]$ ./a.out

Killed

This is in dmesg:
