Memory corruption via camera image buffer over-read
Published Jul 8, 2025 · Updated Jul 8, 2025
Buffer over-read in Qualcomm Snapdragon camera image encoding allows local users with low privileges to read beyond a buffer and corrupt memory. Qualcomm has not disclosed which encoder function or buffer is involved, what input reaches it, or why the bounds check fails. The documented gate is local low-privileged access without user interaction, and successful exploitation can expose or alter data or crash the affected device.
