CVE-2026-102712 | BDVDB-2026-380968 Detail

Description#

In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, built with DTLS server support, the NetX Secure DTLS server's ClientHello parser reads the session ID, cookie and ciphersuite list without bounding them by the bytes remaining in the message. An unauthenticated peer can send a ClientHello declaring fields longer than the message and make the server read past it; nothing read is sent back to the peer, and the read can fault the server only on targets that trap the address beyond the buffer.
