CVE-2026-1519

HIGHEPSS 75th pctl

7.5

CVSS v3

Description

If a BIND resolver is performing DNSSEC validation and encounters a maliciously crafted zone, the resolver may consume excessive CPU. Authoritative-only servers are generally unaffected, although there are circumstances where authoritative servers may make recursive queries (see: https://kb.isc.org/docs/why-does-my-authoritative-server-make-recursive-queries). This issue affects BIND 9 versions 9.11.0 through 9.16.50, 9.18.0 through 9.18.46, 9.20.0 through 9.20.20, 9.21.0 through 9.21.19, 9.11.3-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.46-S1, and 9.20.9-S1 through 9.20.20-S1.

Common questions

How do I fix CVE-2026-1519?

Published advisories record a fix for 124 affected products. The "How to fix" section on this page lists the fixed version and source advisory for each one, so apply the entry matching what you actually run.

Is CVE-2026-1519 being actively exploited?

Not that we know of. CVE-2026-1519 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 1.6% is the estimated probability that it will be exploited in the next 30 days. That is higher than 75% of all scored CVEs.

How severe is CVE-2026-1519?

CVE-2026-1519 has a CVSS v3 base score of 7.5, rated high. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.

What does CVE-2026-1519 affect?

Published advisories record a fix for bind9 (Debian), bind (Red Hat / RHEL), bind (Rocky), bind-chroot (Red Hat / RHEL), and 120 more. Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.
