CVE-2025-58316 is a denial-of-service vulnerability identified in Huawei's HarmonyOS, specifically within the video-related system service module. The root cause is a race condition (CWE-362) stemming from improper synchronization when multiple concurrent executions access shared resources. This flaw can be triggered by an attacker with local access to the device, without requiring any privileges or user interaction, making exploitation relatively straightforward. When exploited, the vulnerability can cause the video system service to crash or become unresponsive, leading to a denial of service that affects the availability of video functionalities on the device. The affected HarmonyOS versions include 5.0.1, 5.1.0, and 6.0.0, which are deployed on various Huawei devices. The CVSS v3.1 base score is 7.3, indicating high severity, with the vector highlighting local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). Confidentiality and integrity impacts are limited but present, while availability impact is high. No public exploits have been reported yet, and no patches are currently linked, suggesting that mitigation relies on vendor updates and defensive controls. The vulnerability underscores the risks of concurrency issues in system services, particularly in critical modules like video processing that are integral to user experience and device functionality.

For European organizations, the primary impact of CVE-2025-58316 is the potential disruption of video-related services on Huawei devices running the affected HarmonyOS versions. This can affect communication, surveillance, and multimedia applications that rely on stable video system services, leading to operational downtime and degraded user experience. In sectors such as telecommunications, public safety, and enterprises using Huawei hardware for video conferencing or monitoring, this DoS could interrupt critical workflows. Although the vulnerability does not directly compromise data confidentiality or integrity to a large extent, the loss of availability can have cascading effects on business continuity and service reliability. Given the local attack vector, insider threats or compromised local access points pose a risk. The absence of known exploits reduces immediate threat but does not eliminate the risk of future weaponization. Organizations with Huawei devices should be vigilant, especially where video services are mission-critical. The impact is heightened in environments where patching is delayed or device management is decentralized.

1. Monitor Huawei’s official security advisories closely and apply patches promptly once released to address this vulnerability. 2. Restrict local access to devices running affected HarmonyOS versions by enforcing strict physical security and limiting user permissions to trusted personnel only. 3. Implement endpoint detection and response (EDR) solutions capable of monitoring system service crashes or anomalies related to video modules. 4. Use application whitelisting and process monitoring to detect unusual concurrent execution patterns that may indicate exploitation attempts. 5. Conduct regular audits of device configurations and user access controls to minimize the risk of unauthorized local exploitation. 6. For organizations relying heavily on video services, consider deploying redundant systems or failover mechanisms to maintain availability during potential DoS events. 7. Educate staff about the risks of local exploitation and ensure that devices are not left unattended in insecure environments. 8. Collaborate with Huawei support channels to gain early access to patches or workarounds and share threat intelligence within industry groups.
