Openharmony

OpenHarmony versions 5.1.0 and prior contain an improper input validation vulnerability (CWE-20) that allows local attackers with low privileges to trigger a denial of service condition. An authenticated local user can craft malicious input that causes the system to become unresponsive or crash, requiring manual intervention to restore availability. While this vulnerability has a moderate CVSS score of 5.0, the local-only attack vector and requirement for user interaction limit widespread exploitation risk.

An out-of-bounds write vulnerability (CWE-787) exists in OpenHarmony versions up to and including v5.1.0, enabling local attackers to execute arbitrary code within pre-installed applications. The vulnerability requires local access and low privileges but can result in complete confidentiality compromise. This is a memory corruption issue that, while restricted to specific scenarios, poses a meaningful risk to OpenHarmony device security given the local attack vector and high impact on confidentiality.

An out-of-bounds write vulnerability in OpenHarmony v5.1.0 and earlier versions allows local attackers with limited privileges to achieve arbitrary code execution within pre-installed applications through memory corruption. The vulnerability, tracked as CVE-2025-41432 and assigned CVSS 5.5, exploits CWE-787 (out-of-bounds write) and is limited to restricted attack scenarios that require local access and low privilege levels. While not currently listed in CISA's Known Exploited Vulnerabilities (KEV) catalog, the availability of vulnerability disclosure documentation and the nature of memory corruption bugs suggest heightened risk for motivated threat actors.

This vulnerability allows arbitrary code execution in OpenHarmony pre-installed applications through improper handling of incompatible types, enabling local attackers to escalate privileges and execute arbitrary code within the context of trusted system applications. Affected versions include OpenHarmony v5.0.3 through v5.1.0.x, impacting the core application framework across the OpenHarmony ecosystem. While the CVSS score of 6.3 reflects moderate severity, the vulnerability requires local access and high attack complexity, limiting real-world exploitability to restricted scenarios as noted by the vendor.

OpenHarmony versions 5.0.3 and earlier contain an information disclosure vulnerability caused by use of uninitialized resources, allowing local attackers to leak sensitive case-sensitive data. The vulnerability affects OpenHarmony deployments across all product lines up to v5.0.3.x (per EUVD-2025-208673). An attacker with local access and standard user privileges can read uninitialized memory regions to obtain confidential information without requiring user interaction, though there is no indication of active exploitation in public KEV databases at this time.
