# CVE-2014-9322 PoC for Linux kernel
CVE-2014-9322 (a.k.a BadIRET) proof of concept for Linux kernel.
This PoC uses only syscalls not any libraries, like pthread. Threads are implemented using raw Linux syscalls.
[Raw Linux Threads via System Calls](http://nullprogram.com/blog/2015/05/15/)
# Usage
```
$ make
```
**badiret.elf** is an ELF executable.
**badiret.bin** is a raw binary that can be used as payload.
