CVE-2025-23418

Local service interruption via out-of-bounds read

Published Mar 4, 2025 · Updated Mar 11, 2025

Out-of-bounds read in OpenHarmony 4.1.0 through 5.0.2 allows local users to interrupt the Arkcompiler ETS Runtime service. OpenHarmony identifies the Arkcompiler ETS Runtime as the affected locus but does not disclose the function, input, or missing bounds operation that triggers the read. Low-privileged local access is required, no user interaction is needed, and the documented consequence is limited to availability loss.
