🚨High - Knot Resolver DNS-over-QUIC Heap Overflow Remote Code Execution (CVE-2026-66374) Knot Resolver before 6.4.1 contains a heap-based buffer overflow in its DoQ (DNS-over-QUIC) receive path, reachable by an unauthenticated remote attacker and leverageable for remote code execution. Because Knot Resolver is internet-facing DNS infrastructure used by ISPs and enterprises, compromise of the resolver is a core-network trust event - an attacker could disrupt or redirect DNS for everyone behind it. Only deployments with the DoQ listener enabled are affected, and attack complexity is high, but a public PoC exists. CVSS 8.1. 👉Upgrade Knot Resolver to 6.4.1. If you can't patch immediately, disable the DNS-over-QUIC (DoQ) listener.
Post summary
CVE-2026-66374 is a heap‑overflow RCE in Knot Resolver’s DNS‑over‑QUIC that has a publicly documented PoC, and it can be mitigated by upgrading to 6.4.1 or disabling the DoQ listener.
