Kextstat ASLR

A small util to list OS X kernel extensions with true addresses.
System kextstat util doesn't return info with kernel ASLR slide.
 
(c) fG!, 2012, 2013, 2014 - reverser@put.as - http://reverse.put.as
 
Uses processor_set_tasks() vulnerability or /dev/kmem to 
read kernel memory.

If processor_set_tasks() vuln not available you need to enable /dev/kmem.
Edit /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
add kmem=1 parameter, and reboot!

This version can work with all Mountain Lion/Mavericks versions out of the box.
It should work with any future OS X versions if OSArray class doesn't change.

The license is GPLv3 due to diStorm licensing terms.

Enjoy,
fG!


Change log:

v0.1 - Initial version
v0.2 - Retrieve kaslr slide via kas_info() syscall. Thanks to posixninja for the tip :-)
v0.3 - Cleanups
v1.0 - Use diStorm to find sLoadedKexts so everything is dynamic
       The only dependency is on OSArray class, since we are using fixed offsets
v1.1 - Try to use processor_set_tasks() vulnerability to read kernel memory
       before trying to use /dev/kmem
