This is a XNU (IOKit) kernel extension inspired by the hacksysteam/HackSysExtremeVulnerableDriver written by me (TrungNguyen1909)

ExtremeVulnerableDriver is intentionally vulnerable XNU driver developed for security enthusiasts to learn and polish their exploitation skills at Kernel level.

• Stack buffer overflow (based on matesCTF's KSMASH Linux kernel Exploit challenge)

• Heap buffer overflow (stereo-typed version of IOAccelerationFamilyV2. replica of CVE-2020-3837 bug)

• The one I accidentially made and haven't noticed yet.

The task is simple: Elevate to root. TFP0 if possible.

Solutions for vulnerabilties are put inside exploits folder. Please include the vulnerability's name you exploited, the macOS build version and first 6 characters of the sha1 of the driver's commit that you worked on in the file name.

This is because offsets may be subjected to changes between macOS or driver version.

Are welcome (including driver code and exploits)
