CVE-2026-102720

A DHCP server, or anyone on the LAN who answers a DISCOVER first, can make the client read about a kilobyte past the end of the received message. The option walk keeps a pointer and an offset in step, and the only bound check uses the offset: c / addons/dhcp/nxddhcpclient.c:7538, 7572 / while i...

CVE-2026-102720

The NetxDuo DHCP client is vulnerable to a heap-buffer-overflow due to an incorrect bound check in addons/dhcp/nxd_dhcp_client.c. When parsing TLV options, the pointer data is advanced by size + 2 bytes, but the loop counter i is only advanced by size + 1 bytes. This discrepancy allows a hostile ...

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...

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-2026-102713

The NetX Duo TFTP server is vulnerable to a heap-buffer overflow and a denial-of-service condition due to a missing upper-bound check on incoming DATA datagrams . Because the server fails to validate that nx_packet_length is within the protocol maximum of 4 + NX_TFTP_FILE_TRANSFER_MAX, it allows ...

CVE-2026-102713

The TFTP server accepts a DATA datagram of any size. The dispatcher rejects datagrams shorter than four bytes nxdtftpserver.c:1037 and nothing anywhere checks an upper bound, in particular not against the protocol maximum of 4 + NXTFTPFILETRANSFERMAX. Two things follow from that one missing check...
