          "details": "This flaw is a read‑only, 10‑byte heap out‑of‑bounds disclosure with no write, code‑execution, or denial‑of‑service path, so any confidentiality impact is minimal and unreliable for extracting meaningful secrets. Successful exploitation assumes a malicious authoritative NXDOMAIN with crafted NS/authority fields, but dnsmasq functions as a forwarding cache and only accepts replies from its configured upstream recursive resolvers, preventing an attacker‑controlled authoritative server from directly supplying the malformed wire image and materially reducing real‑world exploitability. Instances using dnsmasq purely as a forwarder to trusted upstream resolvers and not performing full recursion can therefore safely deprioritize this CVE.",
