CVE-2023-52357

Service interruption via vibration-framework serialization mismatch

Published Feb 18, 2024 · Updated Dec 5, 2024

Deserialization mismatch in the Huawei EMUI and HarmonyOS vibration framework allows attackers to interrupt affected service availability. Huawei identifies inconsistent serialization and deserialization in that framework but has not disclosed the data flow, entry point, or failing operation. Public assessments disagree on remote versus local reachability; both require no privileges or interaction and limit the consequence to availability.
