Over 100 Vulnerabilities Identified in LTE and 5G Networks

📡 Over 100 security vulnerabilities threaten LTE and 5G networks. Researchers from the University of Florida and North Carolina State University have identified 119 vulnerabilities across various LTE and 5G implementations, which could allow attackers to disrupt cellular services and infiltrate core networks. The vulnerabilities, detailed in the study “RANsacked,” affect seven LTE and three 5G systems, with many linked to buffer overflows and memory corruption. Attackers could exploit these flaws to crash critical network components like the Mobility Management Entity (MME) and Access and Mobility Management Function (AMF) using unauthenticated access. The findings highlight significant security risks, particularly with the increasing accessibility of base stations and femtocells, which expose previously secure network elements to potential threats.
