// CVE-2025-62470 PoC - Windows CLFS Driver Heap Overflow
// This is a conceptual PoC for educational purposes only
#include <windows.h>
#include <stdio.h>
// CLFS log file structures would be defined here
// The PoC would need to:
// 1. Open or create a CLFS log file
// 2. Manipulate log record structures to trigger overflow
// 3. Overwrite heap metadata to achieve arbitrary write
// 4. Use kernel payload to escalate privileges

printf("CVE-2025-62470 PoC\n");
printf("Target: Windows CLFS Driver (clfs.sys)\n");
printf("Vulnerability: Heap-based buffer overflow\n");
printf("Impact: Local privilege escalation\n");
// Note: Actual exploitation requires:
// - Detailed knowledge of CLFS internal structures
// - Heap spray techniques for kernel pool
// - Kernel payload development
// - Bypassing kernel security mitigations (KASLR, SMEP, etc.)
printf("\nThis vulnerability requires careful heap grooming");
