CVE-2025-20024

Local code execution via Arkcompiler integer overflow

Published Mar 4, 2025 · Updated Mar 4, 2025

Integer overflow in OpenHarmony 4.1.0 through 5.0.2 allows local users to execute arbitrary code in pre-installed applications. OpenHarmony identifies Arkcompiler Ets Runtime as the affected component but has not disclosed the overflowing operation or attacker-controlled input. Low local privileges and restricted, unspecified conditions are required; the vendor reports confidentiality impact across a security boundary.
