CVE-2016-4669

Imperfect exploit code, for learning purposes only :)

#1 Compilation method Just run make

#2 Function If successful, it can obtain root privileges. But the success rate is not high.

#3 General overview

• Relatively stable creation of a dangling port.
• Cannot stably reuse the port with root privileges; succeeds about 1 in 10 times :(, possibly lower.
• Not very stable, easily crashes the kernel. Only for understanding and analyzing the cause and exploitation principle of this vulnerability.
• Should not be further improved, but still hope an expert can point out a more stable triggering method.
