CVE-2025-0302 affects OpenHarmony versions 4.1.2 and prior, allowing local attackers to exploit an integer overflow vulnerability. This type of vulnerability can lead to a denial of service (DoS), affecting the availability of the system. With a CVSS score of 5.5, this vulnerability is classified as medium severity, indicating a moderate level of risk for organizations that utilize this technology.
Risk to organizations includes potential downtime and operational disruption, especially if exploited in sensitive environments. As the availability impact is rated high, organizations should prioritize patching immediately to prevent potential service interruptions.
Currently, there are no known public exploits or proofs of concept for this vulnerability. However, the attack vector is local, which means that an attacker must have local access to the system to exploit this vulnerability. As such, the urgency for defenders to address this vulnerability is classified as moderate.
Organizations should assess their deployment of OpenHarmony and implement necessary patches to mitigate risks associated with CVE-2025-0302.
Vulnerability Details
The official description states that this vulnerability allows a local attacker to cause a denial of service through integer overflow in OpenHarmony versions 4.1.2 and prior. The CVSS score of 5.5 categorizes this as a medium severity vulnerability, primarily impacting availability without affecting confidentiality or integrity.
The weakness is classified under CWE-190, indicating that it is associated with integer overflow issues, which can often lead to unexpected behaviors in software applications.
Technical Analysis
The root cause of this vulnerability lies in the handling of integer values within the affected versions of OpenHarmony. The vulnerability can be exploited through a local attack since the attack vector is classified as local, indicating that the attacker must have access to the target system.
The attack complexity is low, and privileges required for exploitation are also low. Importantly, user interaction is not required to trigger the vulnerability, making it easier for an attacker to exploit. The availability impact is rated high, meaning that successful exploitation can lead to significant downtime for the affected services.
Risk & Impact Analysis
Organizations deploying OpenHarmony should recognize the potential risks associated with this vulnerability. Given the high impact on availability, organizations could face significant service disruption if exploited. The medium severity level indicates that while immediate action may not be critical, it is essential to address this vulnerability in a timely manner.
In light of the CVSS score and current exploitation status, organizations should schedule remediation in their patch management cycle to mitigate the risks associated with CVE-2025-0302. The potential blast radius could affect multiple systems if not addressed promptly.
