clabCVCRootCACert
Module: CLAB-DEF-MIB
OID (symbolic): CLAB-DEF-MIB::clabCVCRootCACert
OID (numeric): 1.3.6.1.4.1.4491.3.1.2
Node type: OBJECT-TYPE
Type: DocsX509ASN1DEREncodedCertificate
Access: read-only
Description: The X509 DER-encoded CableLabs CVC Root CA Certificate.
What is clabCVCRootCACert?
This read-only object holds the X.509 DER-encoded CableLabs CVC (Code Verification Certificate) Root CA Certificate stored on the device. A security engineer would check it to confirm the device's code-signing trust chain starts from the correct CableLabs root. For example, if firmware signed under a new CVC hierarchy fails to validate on a device, comparing this stored root certificate against the expected one can reveal whether the device's trust anchor is out of date.
