CVE-2025-41432

Local code execution via undisclosed runtime out-of-bounds write

Published Mar 16, 2026 · Updated Mar 16, 2026

Out-of-bounds write in OpenHarmony 5.0.3 through 5.1.0.x allows local users to execute arbitrary code in pre-installed apps. OpenHarmony identifies arkcompiler_ets_runtime as the affected repository but does not disclose the faulty operation, buffer, or triggering input. Exploitation requires local low-privileged access and a restricted scenario; the vendor's impact assessment records confidentiality loss only.
