Preface: When used in an automotive context, the Snapdragon 8 Gen 3 Mobile Platform—and its dedicated automotive counterparts—utilize a High-Level Operating System (HLOS).
While the “Mobile Platform” is a consumer-grade chip typically found in smartphones, some automakers have integrated it directly into vehicles. For purpose-built automotive solutions, Qualcomm offers the Snapdragon Cockpit Elite and Snapdragon Ride Elite, which share the same underlying architecture (Oryon CPU cores) as the mobile 8-series.
Background: The Snapdragon 8 Gen 3 Mobile Platform redefines mobile connectivity with advancements in speed, reliability, and future-proofing. At its core is the Snapdragon X75 5G Modem-RF System, which delivers high performance, including up to 10Gbps downlink and 3.5Gbps uplink speeds.
While the High-Level Operating System (HLOS) allocates a non-secure buffer to communicate with the Trusted Execution Environment (TEE), this buffer is only used for passing encrypted payloads, commands, or non-sensitive handshake parameters.
The Automotive smart cockpit is an advanced integrated digital environment that uses artificial intelligence, sensors and connectivity to unify the driver interface, infotainment and vehicle controls, transforming the cabin into a personalized interactive space for driving, entertainment and productivity.
HDCP is used in smart cockpits to protect high-resolution digital video and audio content transmitted across internal digital interfaces like HDMI, DisplayPort, and automotive-specific links such as APIX (Automotive Pixel Link ) or GMSL (Gigabit Multimedia Serial Link).
HDCP in Automotive Platforms (HDCP) is a link protection protocol, and its security depends on proper key management and session handling inside the TEE.
- The session keys are stored securely in TEE and referenced by session ID.
- There’s no indication that the same nonce or key pair is reused across sessions or encryption operations.
- The non-secure buffer is freed after the session ends, which is good practice.
Vulnerability details: Cryptographic issue may occur while encrypting license data. The potential vulnerability (CVE-2025-47345) in Qualcomm Snapdragon platforms arises from reusing a nonce or key pair during encryption, violating cryptographic best practices (CWE-323). This issue is not an application-level flaw but a platform design decision.
As a matter of fact, modern threat models consider:
• TEE compromise or privilege escalation as realistic attack vectors.
• Static cryptographic material as a critical weakness, enabling replay attacks, impersonation, or content decryption.
