Overview of CVE-2025-24301
The vulnerability identified as CVE-2025-24301 in the OpenHarmony system poses a risk for devices operating with this platform. Specifically, versions up to v5.0.2 are susceptible to a Use After Free (UAF) condition. This vulnerability can allow local attackers to execute arbitrary code within pre-installed applications, although it only becomes exploitable in certain restricted scenarios.
Technical Details
Rooted in the Arkcompiler Ets Runtime, this flaw earns its severity from its classification as a Use After Free issue, designated under CWE-416. Such vulnerabilities are characterized by the continuous use of memory space after it has been freed, allowing local attackers a foothold to execute arbitrary code. The attack vector remains LOCAL, meaning physical access or proximity to the target device is required.
The CVSS version 3.1 metrics provide us with a base score of 3.8, categorizing the severity as LOW. Despite its low score, it still carries a LOW attack complexity with LOW privileges required for potential exploitation. Its impact, however, affects the confidentiality of a system slightly, without touching on integrity or availability aspects.
Mitigation Strategies
To mitigate this vulnerability effectively, consider the following pathways:
- Patch and Update: Ensure that all systems running OpenHarmony are updated to the latest available version beyond v5.0.2. Check official openHarmony disclosure resources for updates.
- Access Control: Restrict physical access to devices where OpenHarmony is deployed. Constant audit and monitoring of access logs can help identify unusual activities.
- Code Audits: Regularly perform code assessments and audits focusing on memory management and resource cleanup in applications that may utilize Arkcompiler Ets Runtime.
- Security Training: Educate stakeholders and users on the risks associated with Use After Free vulnerabilities and best practices in device handling and security.
Conclusion
While CVE-2025-24301 might be moderately severe, the implied risk through local exploitation mandates proactive defense mechanisms such as timely updates, access control, and continuous security assessments. Implementing these measures can considerably mitigate potential exploits deriving from this Use After Free vulnerability.
