Answer in brief
CVE-2026-106464 records a High severity (CVSS 8.7) vulnerability in Out-of-bounds read via an empty signature BIT STRING in NetX Secure X.509 parsing. The current sources do not mark it as known exploited. The current feed maps Eclipse Foundation/Eclipse ThreadX NetX Duo (generic), Eclipse Foundation/NetX Duo (generic). Check affected ranges and fixed versions before updating.

HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 8.7. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
