| CVE-2026-93475 | Cri | 0.60 | — | 0.00 | Oct 20, 2026 | The X.509 parser in NetX Secure accepts an RSA public key of any size, but every signature-verification path decrypts into fixed-size buffers dimensioned for the `NX_CRYPTO_MAX_RSA_MODULUS_SIZE` default of 4096 bits. A certificate carrying a larger modulus drives an… | ||
| CVE-2026-103415 | Cri | 0.60 | — | 0.00 | Oct 14, 2026 | When a TLS 1.3 client processes a HelloRetryRequest, it copies the server's cookie into its second ClientHello without checking that the cookie fits in the outgoing packet. Both the length and the contents of that cookie come from the peer, and the write happens before… | ||
| CVE-2026-103416 | Cri | 0.60 | — | 0.00 | Oct 7, 2026 | Out-of-bounds write via the TLS 1.3 handshake message cache in NetX Duo in Eclipse ThreadX NetX Duo 6.5.1.202602 allows a handshake message larger than the cache writes past it and on into the rest of the session control block, which holds pointers. A malicious or compromised… | ||
| CVE-2026-102761 | Cri | 0.60 | — | 0.00 | Sep 29, 2026 | NetX Duo's WebSocket client resets the unmasking cursor to the first `NX_PACKET` each time it advances through a chained packet, while the loop's upper bound belongs to the current packet. With the standard contiguous packet-pool layout, a masked server frame split across two… | ||
| CVE-2026-92853 | Hig | 0.57 | — | 0.00 | Oct 20, 2026 | The TLS 1.3 Certificate-message parser in NetX Secure decrements the message length to skip a context byte without first establishing that the message has a byte to skip. A zero-length Certificate message therefore wraps the unsigned length to `0xFFFFFFFF`, which makes the… | ||
| CVE-2026-92843 | Hig | 0.57 | — | 0.00 | Oct 20, 2026 | A missing bounds check in the TLS 1.3 Certificate-message parser of NetX Secure lets a malicious TLS 1.3 server trigger an unsigned-integer underflow and a subsequent heap out-of-bounds read in any peer that processes a remote Certificate message. It is reachable… | ||
| CVE-2026-106465 | Hig | 0.57 | — | 0.00 | Oct 14, 2026 | The NetX Secure DTLS server sends a HelloVerifyRequest carrying a freshly generated cookie, but never checks the cookie a client returns. The ClientHello parser copies the client's cookie bytes over the value the server issued, and the server then decides whether the client has… | ||
| CVE-2026-106464 | Hig | 0.57 | — | 0.00 | Oct 14, 2026 | `_nx_secure_x509_parse_signature_data` computes the certificate signature's length as `tlv_length - 1` without first checking that `tlv_length` is non-zero. A certificate whose signature is an empty ASN.1 BIT STRING therefore parses successfully and leaves the certificate… | ||
| CVE-2026-102718 | Hig | 0.57 | — | 0.00 | Sep 29, 2026 | hey, `_nx_snmp_utility_object_id_get` in the NetX Duo SNMP addon does not validate the claimed OID data length against the actual buffer size when the OID uses BER multibyte length encoding, so a remote attacker can send a crafted SNMP packet with a multibyte OID length… | ||
| CVE-2026-102716 | Hig | 0.57 | — | 0.00 | Sep 29, 2026 | An unauthenticated client can drain the RTSP server's packet pool with a couple of dozen requests that carry a Session header the parser cannot convert. The Session branch returns the raw NetX error code instead of an RTSP status code: ```c /*… | ||
| CVE-2026-102713 | Hig | 0.57 | — | 0.00 | Sep 29, 2026 | The TFTP server accepts a DATA datagram of any size. The dispatcher rejects datagrams shorter than four bytes (nxd_tftp_server.c:1037) and nothing anywhere checks an upper bound, in particular not against the protocol maximum of 4 + NX_TFTP_FILE_TRANSFER_MAX. Two things… | ||
| CVE-2026-102712 | Hig | 0.57 | — | 0.00 | Sep 29, 2026 | On the first DTLS ClientHello, the parser copies a device-claimed session_id length and validates the ciphersuite-list length against the total record length instead of the remaining bytes. An unauthenticated peer drives an OOB source read of up to 255 bytes, and those… | ||
| CVE-2026-102762 | Hig | 0.53 | — | 0.00 | Sep 29, 2026 | The NetX Duo MQTT client leaks the packet carrying a malformed PUBLISH message. Each malformed PUBLISH costs one packet, or one chain of packets, from the network driver's receive pool, and nothing returns it. A peer that can deliver a few dozen such messages exhausts the pool… | ||
| CVE-2026-94018 | Hig | 0.50 | — | 0.00 | Oct 20, 2026 | The Web add-on's HTTP server dereferences and releases an uninitialized pointer when it detects a `Content-Length` underflow while processing a `PUT` request. The condition is reachable by an unauthenticated remote client with a single malformed request. | ||
| CVE-2026-102717 | Hig | 0.49 | 7.5 | 0.00 | Sep 30, 2026 | MQTT WebSocket setter ABI mismatch may disclose memory or cause a crash | ||
| CVE-2026-102728 | Hig | 0.49 | 7.5 | 0.00 | Sep 29, 2026 | Two client-side TLS/DTLS handshake parsers in NetX Secure read fields from a server-supplied message before validating that the message is long enough to contain them. Both are bounded out-of-bounds reads on a remotely reachable path, both are reached from a TLS or DTLS client… | ||
| CVE-2026-11576 | Hig | 0.49 | 7.5 | 0.00 | Jun 19, 2026 | The security fix for CVE-2025-0728 in eclipse-threadx NetX Duo refactors error handling in the HTTP server PUT process to use a shared cleanup label, but this unified cleanup path unconditionally calls fx_file_close() even when the file was never successfully opened. Multiple… | ||
| CVE-2026-102715 | Hig | 0.46 | — | 0.00 | Sep 29, 2026 | 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/nxd_mdns.c:11436, 11443, 11447 */ memory_len =… | ||
| CVE-2026-102714 | Hig | 0.46 | — | 0.00 | Sep 29, 2026 | `_nx_icmpv6_validate_options()` scans the option area with `while (length > 2)` (`common/src/nx_icmpv6_validate_options.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… | ||
| CVE-2026-102722 | Med | 0.45 | — | 0.00 | Sep 29, 2026 | In the IPv4 PASV path, the FTP Client accepts whatever address was sent in the server's `227` reply. Validation only covers the parse and the non-zero values, thus a malicious server can name any address and direct the Client there. |

In the IPv4 PASV path, the FTP Client accepts whatever address was sent in the server's `227` reply. Validation only covers the parse and the non-zero values, thus a malicious server can name any address and direct the Client there.
