CVE-2026-19667: Numeric Truncation Error

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-2026-81563: Missing Release of Memory after Effective Lifetime

A BIND resolver encountering an SVCB/HTTPS AliasMode record referencing 14 or more SVCB/HTTPS ServiceMode records may fail to properly deallocate internal resources. If this happens repeatedly, resource exhaustion will eventually prevent the resolver from performing new recursive lookups. This...

CVE-2026-80274: Reachable Assertion

If a BIND resolver sends a query for a DNSSEC-signed authoritative zone, and the authoritative server replies with a valid wildcard answer and signed NSEC3 proof, followed by an unsigned NSEC at the same owner name, it will trigger an unexpected program exit. This issue affects BIND 9 versions...

CVE-2026-19662: Use After Free

An attacker may be able to cause a named resolver to abort. The attack requires inducing the victim resolver to send multiple queries for a DNSSEC-signed zone hosted by an authoritative server under the control of the attacker. If the auth responds with a particular sequence of crafted answers, a...

CVE-2026-19668: Inefficient Algorithmic Complexity

A BIND recursive resolver may experience excessive resource consumption if it encounters large numbers of a particular kind of invalid DNSSEC record. Default limits on "max-records-per-type" and "max-types-per-name" help mitigate the exposure. This issue affects BIND 9 versions 9.11.0 through...

CVE-2026-77119: Origin Validation Error

A validly signed NSEC3 from an unrelated sibling zone may be accepted as an insecurity proof, downgrading a secure delegation and letting a forged unsigned answer through.

CVE-2026-19941: Insufficient Verification of Data Authenticity

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...
