CVE-2025-6969

Service interruption via improper permission preservation

Published Mar 16, 2026 · Updated Mar 16, 2026

Improper permission preservation in OpenHarmony 5.0.3 through 5.1.0.x allows local users to interrupt the ability runtime service. OpenHarmony identifies ability_ability_runtime as the affected component but does not disclose which permission state is preserved incorrectly or how crafted input reaches it. Exploitation requires low local privileges and user interaction; the reported consequence is an availability-only service interruption.
