CVE-2026-102715

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...

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

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...
