When a program needs to generate/retrieve code and run it, several steps are required. The program needs to allocate memory with read, write, and execution permissions, and perhaps remove the write permission
Bypassing CFI
What CFI Is
Control Flow Integrity (CFI) is a security mitigation that protects against control-flow hijacking attacks by checking if function call is valid. Every compiler has its own implementation
