CVE-2026-13204

If a provably insecure domain is covered by both an NSEC and NSEC3 record at the parent, and there exist an RRSIG for only one of these types, then BIND may exit unexpectedly with an assertion while validating this proof. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through...

CVE-2026-10723

BIND may accept incorrect child-zone NSEC3 records as valid, which could allow an attacker to forge authenticated NXDOMAIN responses. This issue affects BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through...

CVE-2026-13204 Unexpected exit in certain situations with NSEC and NSEC3 both present

If a provably insecure domain is covered by both an NSEC and NSEC3 record at the parent, and there exist an RRSIG for only one of these types, then BIND may exit unexpectedly with an assertion while validating this proof. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through...

CVE-2026-11605

The issue is a resource exhaustion vulnerability associated with DNSSEC validation. BIND always validates all RRSIG records in an answer, even if they are not strictly needed. A query to an authoritative server/zone which returns many valid but superfluous RRSIG records causes the validator to...

CVE-2026-11605 Unnecessary validation of DNSSEC signed records

The issue is a resource exhaustion vulnerability associated with DNSSEC validation. BIND always validates all RRSIG records in an answer, even if they are not strictly needed. A query to an authoritative server/zone which returns many valid but superfluous RRSIG records causes the validator to...

CVE-2026-10822

If BIND encounters a particular invalid data structure in a DNS record, it will accept the invalid data, and may subsequently abort and exit. BIND will first need to store a DNS record for a key KEY, DNSKEY, etc.. That key must specify a PRIVATEDNS algorithm 253, and in the algorithm identifier,...

PT-2026-63416

A DNSSEC validating resolver that is under a random subdomain attack against a DNSSEC-signed zone can suffer from runaway memory usage. The attacker needs to be able to send queries faster than the resolver can perform validation. The increased memory usage can be orders of magnitude beyond the...

The vulnerability of the BIND DNS-Sec DNS server’s verification module allows a attacker to cause a service failure.

The vulnerability of the BIND DNS-server’s DNSSEC verification module lies in the lack of checks on input data for cyclic operations. Exploiting this vulnerability allows a malicious actor to cause service failures...

RockyLinux 9 : bind (RLSA-2026:24367)

The remote RockyLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:24367 advisory. bind: BIND 9 server memory exhaustion during GSS-API TKEY negotiation CVE-2026-3039 bind: BIND: Denial of Service via specially crafted DNS messages...

bind: BIND: Denial of Service via maliciously crafted DNSSEC-validated zone

A flaw was found in BIND. A remote attacker could exploit this vulnerability by sending a maliciously crafted DNSSEC-validated zone to a BIND resolver. This could cause the resolver to consume excessive CPU resources, leading to a denial of service DoS for legitimate users...

bind: BIND 9 server memory exhaustion during GSS-API TKEY negotiation

A flaw was found in BIND.
