// CVE-2025-12736 PoC - OpenHarmony Uninitialized Resource Information Disclosure
// This PoC demonstrates triggering uninitialized resource usage in OpenHarmony
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
// Simulated vulnerable function that uses uninitialized resource
void vulnerable_resource_access() {
char buffer[256];

// returns uninitialized kernel/user space memory
printf("[*] Accessing resource without initialization\n");
// Simulate reading from uninitialized buffer
printf("[!] Potential leaked data: %s\n", buffer);
// In real exploit:
// 1. Trigger specific system call in OpenHarmony
// 2. The syscall returns uninitialized kernel buffer
// 3. Read sensitive data from the buffer
// 4. Data may contain: keys, credentials, config, etc.

/*
Real-world exploitation steps:
1. Identify target device running vulnerable OpenHarmony version
2. Obtain local access with low privileges (PR:L)
3. Trigger vulnerable code path via:
- Specific system API calls
- Resource allocation manipulation
- Specific application interactions
4. Capture leaked data from uninitialized resources
5. Extract sensitive information (credentials, keys, configs)
Note: This is a conceptual PoC. Actual exploitation requires
deep understanding of OpenHarmony internals and specific
vulnerable code paths in the target version.
