CVE-2026-106464Out-of-bounds read via an empty signature BIT STRING in NetX Secure X.509 parsing

Descripción

In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, the NetX Secure X.509 parser accepts a certificate whose signature is an empty BIT STRING and records a signature length of 0xFFFFFFFF. A remote peer can present such a certificate during the TLS handshake, before authentication, and make the device read far outside the certificate buffer during signature verification, which is expected to fault.
