CVE Alert: CVE-2025-47327 – Qualcomm, Inc. – Snapdragon

Risk verdict

High risk due to a use-after-free in the camera encoding path that enables memory corruption with local device access; patching should be treated as urgent.

Why this matters

Successful exploitation could allow arbitrary code execution, data exfiltration from camera streams, or denial-of-service on the device. Given the broad Snapdragon presence across smartphones, IoT and embedded Compute platforms, an attacker with local access could leverage a single vulnerable component to impact multiple apps and user privacy.

Most likely attack path

Exploitation requires local access with low privileges and no user interaction. An attacker could deliver a malicious app or module with camera access to trigger the faulty encoding path, causing use-after-free and possible escalation within the camera subsystem. Lateral movement is unlikely beyond the compromised device, but impact to confidentiality, integrity and availability of camera data is high.

Who is most exposed

Devices shipping Qualcomm Snapdragon SoCs with camera stacks are at risk, including consumer Android phones, tablets, IoT devices and edge/industrial platforms that rely on Qualcomm camera pipelines.

Detection ideas

• Kernel or driver crash logs referencing camera encoding or memory corruption.
• Unusual memory allocation/free patterns during image encoding sessions.
• Dmesg/system logs showing camera stack faults or watchdog/force-crash events.
• Reproducible crashes when capturing or processing images in camera apps.
• Anomalous camera process terminations without clear user action.

Mitigation and prioritisation

• Apply the Qualcomm security bulletin patch (and OS vendor updates) addressing this use-after-free in the camera path.
• If patching is delayed, disable or constrain camera encoding features, and tighten camera permission and app isolation; monitor for abnormal camera activity.
• Validate firmware/driver updates in a controlled test before broad rollout; coordinate with hardware vendors for timely fixes.
• Change-management: schedule within the next maintenance cycle; ensure compatibility with camera apps and enterprise devices.
• Prioritisation note: treat as priority 1 if KEV is true or EPSS ≥ 0.5; otherwise maintain high risk and seek rapid patch adoption.
