CVE-2026-92853
CVE-2026-92853 · Out-of-bounds Read via a Zero-length TLS 1.3 Certificate Message in NetX Secure
Esta página presenta datos de fuentes públicas de vulnerabilidades. Consulta el aviso original antes de actualizar.
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 bounds check that follows vacuous and sends the parser reading past the session packet buffer. The trigger is a four-byte handshake header and requires no cryptographic validity. It is reachable pre-authentication.
