CVE-2026-92843 · Out-of-bounds Read via the TLS 1.3 Certificate extensions_length in NetX Secure
This page contains facts from public vulnerability sources. Check the original advisory before updating.
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 pre-authentication, during the normal handshake, before certificate verification completes.
