In this code we first allocate 128kb (0x20000) , then we use mprotect to set the first and the last page with no permissions and make this memory region the thread stack. if the thread overflow the buffer , the process gets a SIGSEGV and if you write a signal handler for that signal , It will run in the problematic thread context so we can catch it

len The length of the range of addresses, in bytes. prot Here is a tutorial on how to accomplish this: Writing a Self-Mutating x86_64 C Program; from the notes on the mprotect manual page: On Linux it is always permissible to call mprotect() on any address in a process's address space (except for the kernel vsyscall area).

Write a user program in evilnull.c that reads some bytes of its own code using a null pointer, prints a few of those The http://siber.cankaya.edu.tr/SystemsProgramming/cfiles/mprotect.c example in Fig. 6 illustrates this technique.

But I'll add a few C-related comments as well. A short code snippet to give you an idea of where this is heading: A successful call to the mprotect function changes the protection flags of at least length bytes of memory, starting at address. address must be aligned to the page size for the mapping.
