Out-of-bounds writes via unchecked 32-bit buffer sizing
Published Mar 5, 2020 · Updated Aug 5, 2024
Integer overflow in Qualcomm Snapdragon Fingerprint on listed chipsets allows local users to cause out-of-bounds writes on 32-bit builds. The proprietary biometric component fails to validate a buffer size during an integer calculation, so the resulting length permits writes beyond the destination buffer. Exploitation requires local low-privileged access and a 32-bit architecture; published sources do not identify the input path or a more specific consequence.
