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-2026-5172 1 Dnsmasq 1 Dnsmasq 2026-05-11 N/A
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-2005-0876 1 Dnsmasq 1 Dnsmasq 2026-04-16 N/A
Off-by-one buffer overflow in Dnsmasq before 2.21 may allow attackers to execute arbitrary code via the DHCP lease file.
