0 CVE-2026-35501 is a vulnerability in NLnet Labs Unbound versions 1.0.1 through 1.26.1 where improper validation of DNSSEC integrity check values can cause the DNSSEC validator to incorrectly treat a configured trust island as insecure. This occurs when Unbound is configured with both a root trust anchor and an additional trust-anchor for an island-of-security zone whose parent is insecure. A malicious actor can exploit this by sending a forged NSEC reply with the SOA bit cleared, causing Unbound to accept and cache the insecure response without proper RRSIG validation.
