Local information disclosure via authorization-module out-of-bounds read
Published May 6, 2025 · Updated Sep 18, 2025
Out-of-bounds read in the authorization module of Huawei HarmonyOS 5.0.0 allows local users to disclose service-confidential data. Huawei has not published the affected function, input path, or bounds-checking error that causes the module to read beyond its intended buffer. Local execution is required, no user interaction is needed, and the published impact is limited to confidentiality without data modification or service interruption.
