| CVE | Sev | CVSS | KEV | Affected versions | Fixed in | Published | Description |
|---|---|---|---|---|---|---|---|
| CVE-2026-5172 | Hig | 7.3 | < 2.92rel2-18.27.1 | 2.92rel2-18.27.1 | May 11, 2026 | A buffer overflow in dnsmasq’s extract_addresses() function allows an attacker to trigger a heap out-of-bounds read and crash by exploiting a malformed DNS response, enabling extract_name() to advance the pointer past the record’s end. | |
| CVE-2026-4893 | Med | 5.3 | < 2.92rel2-18.27.1 | 2.92rel2-18.27.1 | May 11, 2026 | An information disclosure vulnerability in dnsmasq allows remote attackers to bypass source checks via a crafted DNS packet with RFC 7871 client subnet information. | |
| CVE-2026-4892 | Hig | 8.4 | < 2.92rel2-18.27.1 | 2.92rel2-18.27.1 | May 11, 2026 | A heap-based out-of-bounds write vulnerability in the DHCPv6 implementation of dnsmasq allows local attackers to execute arbitrary code with root privileges via a crafted DHCPv6 packet. | |
| CVE-2026-4891 | Med | 5.3 | < 2.92rel2-18.27.1 | 2.92rel2-18.27.1 | May 11, 2026 | A heap-based out-of-bounds read vulnerability in the DNSSEC validation of dnsmasq allows remote attackers to cause a denial of service via a crafted DNS packet. | |
| CVE-2026-4890 | Hig | 7.5 | < 2.92rel2-18.27.1 | 2.92rel2-18.27.1 | May 11, 2026 | A Denial of Service (DoS) vulnerability in the DNSSEC validation of dnsmasq allows remote attackers to cause a denial of service via a crafted DNS packet. | |
| CVE-2026-2291 | Hig | 7.3 | < 2.92rel2-18.27.1 | 2.92rel2-18.27.1 | May 11, 2026 | dnsmasqs extract_name() function can be abused to cause a heap buffer overflow, allowing an attacker to inject false DNS cache entries, which could result in DNS lookups to redirect to an attacker-controlled IP address, or to cause a DoS. | |
| CVE-2026-6507 | Hig | 7.5 | < 2.92rel2-18.27.1 | 2.92rel2-18.27.1 | Apr 17, 2026 | A flaw was found in dnsmasq. A remote attacker could exploit an out-of-bounds write vulnerability by sending a specially crafted BOOTREPLY (Bootstrap Protocol Reply) packet to a dnsmasq server configured with the `--dhcp-split-relay` option. This can lead to memory corruption, ca |
