| CVE-2026-12725 | 3 Dnsmasq, Redhat, Thekelleys | 5 Dnsmasq, Enterprise Linux, Openshift and 2 more | 2026-06-24 | 5.9 Medium |
| 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. | ||||
| CVE-2026-12969 | 3 Dnsmasq, Redhat, Thekelleys | 5 Dnsmasq, Enterprise Linux, Openshift and 2 more | 2026-06-24 | 5.3 Medium |
| An out-of-bounds read vulnerability exists in dnsmasq's find_soa() function in src/rfc1035.c. When parsing NS section records, extract_name() is called with extrabytes=0, failing to validate that 10 additional bytes exist for fixed-length DNS record fields. A remote attacker controlling a DNS zone can exploit this via a crafted NXDOMAIN response to cause a 10-byte heap out-of-bounds read, potentially accessing stale data from prior transactions. | ||||
| CVE-2020-37127 | 1 Dnsmasq | 1 Dnsmasq | 2026-02-06 | 5.5 Medium |
| Dnsmasq-utils 2.79-1 contains a buffer overflow vulnerability in the dhcp_release utility that allows attackers to cause a denial of service by supplying excessive input. Attackers can trigger a core dump and terminate the dhcp_release process by sending a crafted input string longer than 16 characters. | ||||
| CVE-2025-12200 | 1 Dnsmasq | 1 Dnsmasq | 2025-11-03 | 3.3 Low |
| ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn by its CNA. Further investigation showed that it was not a security issue. Notes: Based on the analysis by MITRE and review of community feedback, the reported conditions represent expected and intentional behavior within dnsmasq's documented design, rather than security vulnerabilities. | ||||

| CVE-2005-0876 | 1 Dnsmasq | 1 Dnsmasq | 2025-04-03 | N/A |
| Off-by-one buffer overflow in Dnsmasq before 2.21 may allow attackers to execute arbitrary code via the DHCP lease file. | ||||
| CVE-2006-2017 | 1 Dnsmasq | 1 Dnsmasq | 2025-04-03 | N/A |
| Dnsmasq 2.29 allows remote attackers to cause a denial of service (application crash) via a DHCP client broadcast reply request. | ||||
