Local denial of service via buffer overflow
Published May 6, 2025 · Updated May 6, 2025
Buffer overflow in arkcompiler_ets_runtime in OpenHarmony 4.1.0 through 5.0.3 allows local users to interrupt a service. OpenHarmony identifies the affected runtime component but has not disclosed the function, buffer, or unchecked copy operation involved. Low-privilege local access is required without user interaction, and the reported consequence is limited to reduced availability rather than data access or modification.
