Service unavailability via DDMP/ODMF hijacking
Published Nov 9, 2022 · Updated May 1, 2025
Service hijacking in Huawei HarmonyOS 2.0 and 2.1 and EMUI 11.0.1 through 12.0.1 allows remote attackers to cause service unavailability. Huawei identifies the DDMP/ODMF module as the affected locus but has not published the specific hijacking operation or input path. The bulletin provides no requirement for authentication or user interaction, and the documented consequence is interruption of service availability rather than data disclosure or modification.
