Out-of-bounds write via DSP integer overflow
Published Apr 11, 2022 · Updated Aug 3, 2024
Integer overflow in the DSP driver in Samsung Mobile Devices on Android 10–12 allows local users to perform an out-of-bounds write. The driver accepts an insufficiently validated integer input, and its overflow causes a write beyond the intended memory bounds. Reachability requires local low-privileged access to an Android 10–12 device using an Exynos 2100, 9830, or 980 chipset; Samsung has not disclosed the exact input path or any further outcome.
