CVE-2026-34671 CAI Content Credentials 整数溢出漏洞

# This is a conceptual PoC for Integer Overflow leading to DoS # Language: Python (Conceptual) def trigger_overflow(data_size): try: # Simulating a scenario where size is used for allocation or loop # If data_size is extremely large, it might wrap around or cause memory error if data_size > 0xFFFFFFFF: # Simulated overflow condition size = data_size & 0xFFFFFFFF # Wraparound else: size = data_size print(f"Allocating buffer with size: {size}") # In a real vulnerability, this might cause a crash due to # malloc failure or buffer overflow if size wraps to a small positive number # but the actual data copied is huge. buffer = ['A'] * size print("Operation successful (Vulnerability not triggered in this safe simulation)") except MemoryError: print("Denial of Service: Memory allocation failed due to large size.") except Exception as e: print(f"Crash occurred: {e}") # Attempting to trigger with a large value # In a real exploit, this would be crafted to hit the specific vulnerable function trigger_overflow(0xFFFFFFFFFFFFFFFF)
