Description
This security bulletin contains information about 1 security vulnerability.
1) Resource exhaustion (CVE-ID: CVE-2026-1519)
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to improper input validation in the DNSSEC validation component when handling NSEC3 records during insecure delegation validation. A remote attacker can send a specially crafted DNS zone response to cause excessive CPU load on the resolver.
Resolvers performing DNSSEC validation are affected; authoritative-only servers are generally not affected unless they perform recursive queries.
