The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly. Security Fix(es): * bind: BIND 9 server memory exhaustion during GSS-API TKEY negotiation (CVE-2026-3039) * bind: BIND: Denial of Service via specially crafted DNS messages (CVE-2026-5946) * bind: bind9: DNSSEC Validation Bypass via Out-of-Zone NSEC Next Field (CVE-2026-13321) * bind: bind9: Potential memory usage beyond configured limits (CVE-2026-11622) * bind: bind9: Cache poisoning via label count discrepancy, RRSIG, wildcards (CVE-2026-11721) * bind: bind9: Unexpected exit with NSEC and NSEC3 both present (CVE-2026-13204) * bind: bind9: Incorrect acceptance of NSEC3 records (CVE-2026-10723) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Multiple flaws have been identified in `named` related to the handling of DNS messages whose CLASS is not Internet (`IN`) — for example, `CHAOS` or `HESIOD`, or DNS messages that specify meta-classes (`ANY` or `NONE`) in the question section. Specially crafted requests reaching the affected code paths — recursion, dynamic updates (`UPDATE`), zone change notifications (`NOTIFY`), or processing of `IN`-specific record types in non-`IN` data — can cause assertion failures in `named`. This issue affects BIND 9 versions 9.11.0 through 9.16.50, 9.18.0 through 9.18.48, 9.20.0 through 9.20.22, 9.21.0 through 9.21.21, 9.11.3-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.48-S1, and 9.20.9-S1 through 9.20.22-S1.
