CVE Alert: CVE-2025-47314 – Qualcomm, Inc. – Snapdragon

Risk verdict

High risk: local attacker could trigger memory corruption via the FE driver, potentially leading to full device compromise; no user interaction required.

Why this matters

Improper input validation enables memory corruption with complete impact on confidentiality, integrity and availability. In automotive platforms, a compromised FE driver could affect critical subsystems and safety‑related functions, with potential persistence across onboard ECUs and connected vehicle networks.

Most likely attack path

An attacker with local access crafts and submits data to the FE driver; insufficient input validation triggers memory corruption. This could allow exploitation with low privileges and no user interaction, potentially elevating access within the platform and enabling broader subverts of connected subsystems.

Who is most exposed

Snapdragon automotive platforms running QNX in ECUs such as infotainment, telematics, or domain controllers are most at risk, especially where the FE driver interface is exposed or poorly isolated.

Detection ideas

• Kernel/driver panics and memory corruption crash dumps tied to FE driver activity.
• Abnormal FE data path events or high fault rates in memory-management logs.
• Unusual or out-of-bounds data processed by the FE driver; unexpected privilege escalations.
• Anomalous traffic to the FE interface or malformed input sequences.
• Post-processing in-vehicle network anomalies following FE data handling.

Mitigation and prioritisation

• Apply vendor patch per Qualcomm security bulletin; upgrade affected versions.
• Enforce least privilege for the FE driver and restrict data sources to the minimum required.
• Harden input validation in the FE driver with strict bounds checking; consider input sanitisation.
• Enable memory-protection features and robust crash/log analytics; mandate secure boot where possible.
• Change-management: schedule testing in QA, validate infotainment/telematics functions, and deploy in a controlled maintenance window.
• If KEV is true or EPSS ≥ 0.5, treat as priority 1. If not, maintain high priority given CVSS 7.8.
