CVD (Coordinated Vulnerability Disclosure)

Also known as: Coordinated Vulnerability Disclosure, Responsible Disclosure

CVD is the process by which vulnerability researchers, affected vendors and, when relevant, coordinators (CSIRTs, GSMA T-ISAC, national authorities) work together to fix a vulnerability and disclose it in a way that minimises risk to users. In telecom, CVD typically covers signaling stack flaws, RAN and core network products, and is increasingly required by regulation such as NIS2 and product security schemes like NESAS.

CVD in context

Telecom threats range from opportunistic SMS phishing and SIM swap to nation-state grade location tracking. The common thread is that most attacks exploit the inherited trust model of legacy signaling protocols.

Telecom networks depend on Internet-style routing (BGP, DNS, MPLS) for interconnect. Route hijacks and DNS abuse can degrade or intercept signaling, which is why RPKI and DNSSEC are now standard hardening for carrier networks.

To place CVD in the wider telecom-security picture, review A5/2, ASN, BGP, BGP Hijacking, CGNAT and CVE — each entry cross-references back to this page so you can walk the topic in either direction.
