CVE-2025-53176

File preview interruption via vector-image stack overflow

Published Jul 7, 2025 · Updated Jul 7, 2025

Stack-based buffer overflow in Huawei HarmonyOS 5.0.1 and 5.1.0 allows local users to disrupt file preview via a crafted vector image. The vector-image parser overflows its stack while generating a file preview; Huawei has not disclosed the responsible function or malformed structure. Low-privileged local access is required, and the reported consequence is limited to interruption of the preview function rather than data disclosure or modification.
