          "details": "This flaw is a small, fixed-size (10‑byte) heap out‑of‑bounds read in dnsmasq’s authority‑section parsing that at most discloses a few stale bytes from prior DNS transactions, with no code execution, data modification, or service disruption. Exploitation also requires the host to actually run dnsmasq as its resolver and to process attacker‑orchestrated lookups for domains the attacker controls; systems not using dnsmasq for resolution are unaffected. Given the confidentiality‑only impact, the tiny and nondeterministic leak, and the specific deployment preconditions, this is reasonable to deprioritize in managed enterprise server/VM environments.",
