CVE-2024-39806

Local information disclosure through out-of-bounds read

Published Oct 8, 2024 · Updated Oct 8, 2024

Out-of-bounds read in OpenHarmony 4.0.0 through 4.1.0 allows local users to disclose information through the LiteOS-A kernel. OpenHarmony identifies LiteOS-A as the affected component but has not published the routine, input path, or missing bounds check that permits the read. Exploitation requires low-privileged local access and affects confidentiality only; no integrity or service-interruption impact is reported.
