CVE-2025-53185

Service integrity compromise via reused virtual addresses

Published Jul 7, 2025 · Updated Jul 7, 2025

Use-after-free in Huawei HarmonyOS 4.0.0 and 4.2.0 and EMUI 14.0.0 allows local users to access released memory. The memory management module reuses a virtual address after its backing memory is released, leaving an invalid reference able to access reallocated memory. Non-privileged local access is required; successful exploitation can corrupt service state and also has limited confidentiality and availability impact.
