CVE-2026-123581 Details

Description

Hickory DNS hickory-proto through 0.26.0-alpha.1 and hickory-net 0.26.0-beta.1 before 0.26.2 contain a DNSSEC validation flaw that accepts a response as a positive answer when any valid RRset appears in the answer section, without checking that the RRset is responsive to the query. Attackers can supply signed but unrelated RRsets so that responses lacking matching records are validated as positive answers instead of as no-data responses.
