CVE (Common Vulnerabilities and Exposures)

Common Vulnerabilities and Exposures is the publicly maintained catalogue of disclosed software vulnerabilities, each assigned a unique CVE-YYYY-NNNN identifier by a CVE Numbering Authority. The system, run by MITRE with CISA sponsorship, is the lingua franca of vulnerability management worldwide and feeds into NVD severity scoring (CVSS) and operator patching workflows.

CVE in context

The radio access network is the layer where mobile devices attach to the operator's infrastructure. Attacks in this layer include IMSI catching, rogue base stations, downgrade attacks and jamming, and defenses hinge on mutual authentication, integrity-protected signaling and Open RAN supply-chain hygiene.

Telecom threats range from opportunistic SMS phishing and SIM swap to nation-state grade location tracking and lawful-interception abuse. The common thread is that most attacks exploit the inherited trust model of legacy signaling. SS7 and Diameter were designed for a closed operator community that no longer exists.

To place CVE in the wider telecom-security picture, review Cybersecurity, Exposure Mapping, RF, ASN, Firmware and IoT.
