CVE-2019-14015

Local memory corruption via unbounded template count

Published Mar 5, 2020 · Updated Aug 5, 2024

A stack-based buffer overflow in Qualcomm Snapdragon fingerprint firmware allows local users to corrupt memory during identification initialization. The identification stage fails to check the supplied number of templates before initializing them, causing writes beyond a stack buffer. Local access to the fingerprint component is required; published sources report memory corruption but do not disclose whether code execution is attainable.
