CVE-2025-25217

Local process crash via NULL pointer dereference

Published Jun 8, 2025 · Updated Jun 9, 2025

NULL pointer dereference in arkui_ace_engine in OpenHarmony 5.0.1 through 5.0.3 allows local users to crash the affected process. OpenHarmony has not published the affected function, triggering input, or operation that leaves the pointer null before dereference. Low-privileged local access is required, and the documented consequence is an availability-only process crash with no confidentiality or integrity impact.
