Annex I Part II requires a coordinated vulnerability disclosure policy, a reporting contact, and measures to facilitate sharing of information about vulnerabilities, including vulnerabilities in third-party components contained in the product. ENISA's vulnerability disclosure material also describes CVD as a multi-party process that coordinates reporting, fixing, mitigation, and public disclosure.
For integrated components, the finished-product manufacturer still has to handle the vulnerability in the finished product. If the component maintainer cannot fix it, the record should show the product-level alternative.
