Source Code is based on the work from here. It's modified to work with Android6.0-rc1 from the Android-x86 project.
PoC for Dirty COW (CVE-2016-5195).
This PoC relies on ptrace (instead of /proc/self/mem) to patch vDSO. It has a
few advantages over PoCs modifying filesystem binaries:
- no setuid binary required
- SELinux bypass
- no kernel crash because of filesystem writeback
And a few cons:
- architecture dependent (since the payload is written in assembly)
- doesn't work on every Linux version
- subject to vDSO changes
