CVE-2024-43696

Local service interruption via undisclosed memory leak

Published Oct 8, 2024 · Updated Oct 8, 2024

Memory exhaustion in OpenHarmony 4.0.0 through 4.1.0 allows local users to interrupt service by triggering a memory leak. The flaw is in the LiteOS_A component, but OpenHarmony has not published the affected function, allocation path, or missing release operation. Low-privileged local access is sufficient, no user interaction is required, and the documented consequence is limited to availability.
