CVE-2025-54629

Service integrity compromise via physical-page import race

Published Aug 6, 2025 · Updated Aug 6, 2025

Race condition in the memory management module of Huawei HarmonyOS and EMUI allows local users to compromise service integrity. During physical-page import, the module improperly synchronizes concurrent access to a shared memory-management resource; Huawei discloses no finer code-level locus. Exploitation requires local access and high privileges, and Huawei reports an integrity impact without describing the exact service data or state that can be altered.
