CVE-2026-19666

On a resolver configured to use dns64, if an applicable answer from the authoritative server is malformed in a specific way, the resolver named process will exit unexpectedly. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1...

CVE-2026-81563

CVE-2026-78301

CVE-2026-77692

An attacker can cause named to abort by sending a crafted DNS-over-HTTPS request with a cryptographically invalid SIG0 record, and then closing the transport connection prematurely. This issue affects BIND 9 versions 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, and 9.20.9-S1 through 9.20.27-S1...

CVE-2026-19941

An inapplicable NSEC record may be accepted by a named resolver as proof that no wildcard exists, which could allow an attacker at the same or an upstream level of the zone name to mask the existence of a victim's wildcard record. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0...

CVE-2026-19662

An attacker may be able to cause a named resolver to abort.

If the auth responds with a particular sequence of crafted answers, a...

CVE-2026-19667

If an attacker-controlled authoritative server can produce a negative answer that is exactly 65536 bytes, then a flaw in named results in a negative cache entry of 0 bytes. When this entry is subsequently read, named aborts. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 throug...

CVE-2026-81736

If a BIND resolver has cached a tree of SVCB/HTTPS AliasMode records, and is then queried for the root of that tree, the resolver will spend disproportionate CPU time constructing the response. This issue affects BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through...
