CVE-2022-42488

Root privilege escalation via unchecked parameter permissions

Published Oct 14, 2022 · Updated May 14, 2025

Missing authorization in OpenHarmony 3.1.2 and earlier allows local users to gain root privileges through the startup subsystem's param service. The service fails to validate an installed application's permission before accepting security-sensitive parameter operations; no public source identifies the affected function or exact request path. An installed malicious application is required, and successful exploitation can disable security features or services, causing a service interruption.
