CVE-2026-102715

A heap-buffer overflow vulnerability exists in the mDNS implementation within NetX Duo (specifically in addons/mdns/nxd_mdns.c). The root cause is a logic error where the string cache lookup compares the rounded slot size rather than the actual string length . This allows names with lengths of 12...

CVE-2026-102715 mDNS string-cache lookup matches on slot size, so a peer name aliases a shorter one and the response encoder writes past the packet

Any host on the LAN can send two mDNS records and make the responder write past the end of its transmit packet. The string table stores each name in a slot rounded up to a multiple of four: c / addons/mdns/nxdmdns.c:11436, 11443, 11447 / memorylen = memorylen & 0xFFFFFFFC + 8 & 0xFFFFFFFF; ... le...
