nasm assembly sys_execve /bin/sh

Question

I'm trying to trigger sys_execve (X86_64).

section .data
file db "/bin/sh",0

section .text
global _start

_start:

mov rax, 59
mov rdi, file
lea rsi, [file] 
mov rdx, 0
syscall

It gives Segmentation fault

What am I doing wrong?

I even tried to put it in a C source:

int main(void)
{
char shellcode[] =
"\xb8\x3b\x00\x00\x00"
"\x48\xbf\xd0\x00\x60\x00\x00"
"\x00\x00\x00"
"\x48\x8d\x34\x25\xd0\x00\x60"
"\x00"
"\xba\x00\x00\x00\x00"
"\x0f\x05";

(*(void (*)()) shellcode)();

return 0;
}

This also gives me a Segmentation fault...

Answer 1

I figured it out:

section .data
file db '/bin/sh',0
file_arg db 'sh',0
argv dq file_arg, 0

section .text
global _start
_start:
mov     rax, 59
mov     rdi, file
mov     rsi, argv
mov     rdx, 0
syscall
