0 A security update for dnsmasq addresses multiple issues including a heap buffer overflow vulnerability (CVE-2026-12725) in the log_query() function when logging unsupported DS/DNSKEY replies. Additional fixes include DNSSEC validation corner cases, DHCPv6 regression, and storage allocation improvements for domain names (CVE-2026-2291).

A heap-based buffer overflow was found in dnsmasq. When DNSSEC validation and query logging are both enabled, logging of DS or DNSKEY replies containing unsupported algorithm or digest types can cause dnsmasq to write past the end of an internal logging buffer. A remote attacker able to supply such a DNS response may crash the dnsmasq process, resulting in denial of service.
