CVE-2026-123592 is fixed in rust-hickory-net on 1 platform by DEBIAN-CVE-2026-123592 (version 0.26.3-1), released November 9, 2026. It is not reported as exploited. Patch Radar priority: Routine.
The hickory-net crate in Hickory DNS 0.26.0-beta.1 before 0.26.2 allows DNSSEC validation bypass because Name's Hash ignores label lengths and ValidationCacheKey compares only that hash. An attacker controlling an unsigned delegation whose name differs from a signed target only in dot positions can prime an Insecure verdict, causing forged answers for the target to skip signature verification instead of returning SERVFAIL.
