CVE-2025-24493

Information disclosure via LiteOS-A kernel race

Published Jun 8, 2025 · Updated Jun 9, 2025

Race condition in the LiteOS-A kernel in OpenHarmony 5.0.1 through 5.0.3 allows local users to disclose sensitive information. OpenHarmony identifies kernel_liteos_a as the affected component but has not published the shared resource, racing operations, or data exposure path. Exploitation requires low-privileged local access and concurrent timing; the documented impact is limited to confidentiality.
