CVE-2020-27904: a tfp0 bug for macOS 10.15.x and below.
Demo exploit code for my [talk](https://www.blackhat.com/asia-21/briefings/schedule/#the-price-of-compatibility-defeating-macos-kernel-using-extended-file-attributes-21799) at BlackHat ASIA 2021.
The vulnerability has been fixed in macOS Big Sur 11.0, and the latest 10.15&10.14 security update.
# Warranty
**Use it on your own risk. This will make you macOS panic.** I build it for security researchers only.

Fix kheap by yourself. I leave it empty on purpose.
