Stack overflow in the ArkCompiler runtime in OpenHarmony 3.2.0 through 3.2.4 allows local users to cause a service crash. OpenHarmony has not published the affected function, triggering input, or unchecked operation beyond identifying a runtime stack overflow. Low-privileged local access is required, and the documented consequence is limited to service availability.
