Preface: Qualcomm provides the Snapdragon Auto 5G Modem-RF (such as the Gen 2 platform) specifically for the automotive industry. For the automotive and EV sector, Qualcomm offers a dedicated platform called the Snapdragon Auto 5G Modem-RF Gen 2. Qualcomm developed the Snapdragon Auto 5G Modem-RF platform (specifically the Gen 2 version) to address the rigorous demands of safety, precise positioning, and integrated computing in the era of Software-Defined Vehicles (SDV).

Background: Snapdragon Auto 5G Modem-RF (Gen 2) supports mission-critical vehicle features such as:

• C-V2X (Cellular Vehicle-to-Everything): Direct communication between vehicles and roadside infrastructure for safety.
• Advanced Positioning: High-accuracy GNSS for autonomous driving and HD mapping.
• Satellite Communications: Support for two-way messaging in remote areas.
• Telematics Framework (TelAF): A specialized development environment for automakers to build connected services.

Ref: A Software-Defined Vehicle (SDV) is an automobile where core features—such as performance, safety, and infotainment—are primarily managed, upgraded, and enhanced through software rather than fixed hardware. By decoupling hardware from software, SDVs enable over-the-air (OTA) updates to add new features or improve functionality throughout the vehicle’s lifespan, functioning more like a smartphone on wheels than a traditional machine.

Vulnerability details: Memory corruption when buffer copy operation fails due to integer overflow during attestation report generation.
