Summary
CVE-2025-0587 is a low-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Openatom Openharmony. Its CVSS base score is 3.8 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 9.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-16 (Memory Protection) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the integer overflow vulnerability by identifying, reporting, and applying patches as provided in the OpenHarmony security advisory.
Implements memory safeguards such as non-executable memory regions to block arbitrary code execution from integer overflow exploitation in pre-installed apps.
Validates information inputs to prevent integer overflows (CWE-190) that enable local attackers to achieve arbitrary code execution.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
CVE-2025-0587 is an integer overflow in arkcompiler_ets_runtime allowing local arbitrary code execution in pre-installed apps under restricted scenarios, enabling exploitation for privilege escalation.
NVD Description
in OpenHarmony v5.0.2 and prior versions allow a local attacker arbitrary code execution in pre-installed apps through integer overflow. This vulnerability can be exploited only in restricted scenarios.
Deeper analysisAI
CVE-2025-0587 is an integer overflow vulnerability (CWE-190) in OpenHarmony versions v5.0.2 and prior. It enables a local attacker to execute arbitrary code within pre-installed applications.
A local attacker with low privileges (AV:L/PR:L) can exploit this vulnerability with low attack complexity and no user interaction required (AC:L/UI:N). Successful exploitation results in a changed scope (S:C) with low confidentiality impact (C:L) and no integrity or availability impact (I:N/A:N), yielding a CVSS v3.1 base score of 3.8. Exploitation is restricted to specific scenarios.
