CVE-2025-0587

Local code execution via undisclosed integer overflow

Published Mar 4, 2025 · Updated Mar 4, 2025

Integer overflow in ArkCompiler ETS Runtime in OpenHarmony 4.1.0 through 5.0.2 allows local users to execute code in pre-installed apps. OpenHarmony has not published the affected function, overflowing arithmetic operation, or attacker-controlled input path. Exploitation requires a low-privileged local context and restricted scenarios; the CNA vector reports only cross-scope confidentiality impact despite the code-execution description.
