GSMA regards the security of mobile network infrastructure and customer equipment such as devices, as essential to the provision of secure and trustworthy services by its members.
The GSMA Coordinated Vulnerability Disclosure (CVD) programme gives security researchers a route to disclose a vulnerability impacting the mobile ecosystem meaning the impact can be mitigated before it enters the public domain. We work with mobile operators, suppliers and standards bodies to develop fixes and mitigating actions to protect customers’ security and trust in the mobile communications industry.
The GSMA encourages disclosure of security research which enhances security levels and better protects assets and customers, and our Coordinated Vulnerability Disclosure programme is designed to support the reporting and remediation of security vulnerabilities at industry level.
We invite both private individuals and organisations to report vulnerabilities to the GSMA in a responsible manner in line with our programme scope.
You can find out more about submitting a vulnerability to the programme here.

Impact of the GSMA CVD Programme
Since our CVD Programme started in 2017 we have considered over 50 vulnerability disclosures, many encapsulating multiple linked vulnerabilities. The technologies have included:
- 2G, 3G, 4G and 5G radio and core networks including Circuit Switched Fallback, IP Multimedia Subsystem, authentication, encryption & unique identifiers
- SIM cards and SIM applets
- Roaming and interconnect
- Wireless Emergency Alerts
The GSMA CVD programme has allowed the industry to improve security in a number of ways thanks to researchers bringing their research on vulnerabilities to the programme prior to public release.
Recent examples include:
- Removal of weak GPRS encryption algorithms from devices and adding respective device test-cases for new devices, prior to the public release of research identifying the weakness. Update of 3GPP specifications within a week of the release of the research (usually takes several months) – research.
- Mandatory inclusion of full-rate user-plane integrity protection for 5G from 3GPP Rel-16, providing protection for an estimated 395 million additional 5G devices – research.
- Issuing of patches to prevent keystream reuse by network equipment that did not following the standards, prior to public presentation of the research. Also included a new SCAS test for this behaviour during NESAS audits – research.
- Inform MNOs about exploitation of SIM cards with a vulnerable applet installed and issue guidance to prevent misuse – research.
Where appropriate, CVD submissions and countermeasures are also added to the relevant GSMA reference document.
