CVE-2026-42304: Twisted Dns Decompression Loopcve-2026-42304-twisted-dns-decompression-loop

DNS decompression parses pointer lengths via offset tracking but lacks loop detection. This allows remote attackers to trigger an infinite loop using deeply chained or cyclic compression pointers, causing a Denial of Service (DoS). Ensure offset references are tracked in a set and reject duplicates.
