gxbinresthemeload sizes its theme buffer for the theme it was asked for, and allocates it even when the resource holds no theme with that id. A theme id at or past the theme count declared by the resource gets a buffer of zero bytes. The load pass then walks past the end of the theme table, takes...

CVE-2026-102729

The function gx_binres_theme_load() is vulnerable to a memory corruption issue where it incorrectly sizes and allocates a theme buffer. When provided with a theme ID that is at or beyond the declared theme count in a resource, the function allocates a zero-byte buffer . The loading process then p...

A TFTP server that answers with a short ERROR packet makes the client read up to 64 bytes past the received datagram. Each receive path checks only that the datagram is at least four bytes long nxdtftpclient.c:1229, 1521, 1984. When the opcode is NXTFTPCODEERROR the message string is copied with ...

CVE-2026-102721

The NetX Duo TFTP client is vulnerable to a heap-buffer-overflow in the nxd_tftp_client.c component. When a remote TFTP server returns an ERROR packet lacking a terminating NUL byte, the client fails to verify the buffer_ptr against the nx_packet_append_ptr during message copying. This causes the...

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-2026-102714

nxicmpv6validateoptions scans the option area with while length 2 common/src/nxicmpv6validateoptions.c:79. An area whose size leaves a one- or two-byte residue exits the loop with that tail unexamined; the residue is not negative, so the function returns NXSUCCESS. Its zero-length rejection never...

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...

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 ...
