CVE-2025-47399

Memory corruption via unchecked sensor-property IOCTL copy

Published Feb 2, 2026 · Updated Feb 2, 2026

Buffer overflow in the camera component of Qualcomm Snapdragon allows local users to corrupt memory through a crafted sensor-property IOCTL. The camera IOCTL handler copies invalid sensor-property input without checking that the destination buffer is large enough. Low privileges are required, and successful corruption can expose or alter protected data or crash the affected device without user interaction.
