Out-of-bounds read in the image codec module in Huawei HarmonyOS 6.1.0 allows local users to disclose service data. Huawei has not published the affected parser or the unchecked operation that makes the codec read beyond a buffer boundary. Exploitation requires local access, needs no privileges or user interaction, and can expose data while causing limited service disruption.
