Reviewed the lockfile-only update and repaired the incompatible mixed Hickory versions by aligning hickory-net, hickory-proto, and hickory-resolver on 0.26.2. Verified official crates.io checksums and dependency constraints. Fresh Cargo check, Clippy, full tests, formatting, pre-commit, Semgrep, and Codecov all pass.

0.26.1→0.26.2Release Notes
hickory-dns/hickory-dns (hickory-resolver)
v0.26.2Compare Source
This release fixes a large number of security vulnerabilities. Most of the issues were related to DNSSEC validation, denial of service and resource consumption attacks, and reachable panics in parsers. Other issues were related to UDP spoofing defenses, caching issues, and general DNS protocol correctness issues.
This is our first post-vulnpocalypse release, and most of these vulnerabilities were discovered through LLM-based workflows. The sheer volume of reports has been a challenge for our volunteer maintainers.
Resolved advisories:
TrustAnchorsdoes not check name of DNSKEYName::hashdiscards label boundaries;ValidationCacheKey(u64)reuses the digest inEqimplementation, leaking an Insecure DNSSEC verdict across distinct owner namesNameServerPool::try_send(resource-exhaustion DoS)Special thanks go out to @qifan-sailboat and Palo Alto Networks for their research and for reporting the bulk of these vulnerabilities. Thanks to @ATinyShoe, @kirk-baird, @thesmartshadow, @BeaCox, @jpds, @N0zoM1z0, and @JasonPap for reporting vulnerabilities as well.
If your organization is interested in coordinated disclosure of future security vulnerabilities, please contact @djc for commercial support.
