CVE-2026-28952 Apple iOS/macOS整数溢出漏洞

# Conceptual Proof of Concept for Integer Overflow # This demonstrates the logic of an integer overflow leading to a crash. # It is not the actual exploit for CVE-2026-28952. def trigger_overflow(size): # Simulate a check that expects size to be small if size < 0: return "Invalid size" # Vulnerable calculation: Adding a header size # If size is very large (near max int), size + 1024 wraps around to a negative or small positive number allocation_size = size + 1024 # The check might pass due to the wrap-around, but actual allocation fails or causes corruption if allocation_size < 0: print("Error: Integer overflow detected in allocation size calculation") # In a real kernel scenario, this leads to a Panic/Crash raise SystemExit else: print(f"Allocating buffer of size: {allocation_size}") # Example input that could trigger the issue (assuming 32-bit signed integer) # Max 32-bit signed int is 2147483647. 2147483647 + 1024 wraps to -2147483625 malicious_input = 2147483647 trigger_overflow(malicious_input)
