CVE-2025-58315 identifies a permissions and access control vulnerability (CWE-264) within the Wi-Fi module of Huawei's HarmonyOS, specifically affecting versions 5.0.1, 5.1.0, and 6.0.0. The vulnerability arises from insufficient enforcement of permission checks, allowing a local attacker without privileges (PR:N) but requiring user interaction (UI:R) to exploit the flaw. The attack vector is local (AV:L), meaning the attacker must have physical or local network access to the device. Successful exploitation leads to a denial of service condition, impacting the availability of Wi-Fi services on the device, but does not compromise confidentiality or integrity of data. The vulnerability is classified as medium severity with a CVSS 3.1 base score of 5.5, reflecting the limited scope and impact. No public exploits or active exploitation have been reported to date. The flaw highlights the importance of robust permission checks in critical modules such as Wi-Fi, which are integral to device connectivity and service continuity. Huawei has not yet published patches, but mitigation will require updates to the affected HarmonyOS versions. The vulnerability’s presence in multiple recent versions indicates a systemic issue in the Wi-Fi module’s permission architecture.

For European organizations, the primary impact of CVE-2025-58315 is the potential disruption of Wi-Fi services on devices running affected versions of HarmonyOS. This could lead to temporary loss of network connectivity, affecting business operations reliant on these devices for communication or IoT functions. Although confidentiality and integrity are not directly impacted, availability degradation can interrupt workflows, especially in environments where HarmonyOS-powered devices are integrated into enterprise networks or critical infrastructure. The requirement for local access and user interaction limits the attack surface, reducing risk from remote attackers but increasing concern in scenarios where devices are physically accessible by unauthorized personnel. Organizations using Huawei devices in sensitive or operational technology contexts should be aware of this vulnerability as it could be leveraged in targeted attacks to cause service outages. The absence of known exploits reduces immediate risk but does not eliminate the need for proactive mitigation.

1. Monitor Huawei’s official security advisories for patches addressing CVE-2025-58315 and apply updates promptly once available. 2. Restrict physical and local network access to devices running HarmonyOS, especially in sensitive or high-security environments, to reduce the risk of local exploitation. 3. Implement strict user access controls and educate users about the risks of interacting with untrusted applications or prompts that could trigger the vulnerability. 4. Employ network segmentation to isolate HarmonyOS devices from critical network segments to limit potential impact of service disruption. 5. Use endpoint detection and response (EDR) tools to monitor for unusual local activity that could indicate attempts to exploit local vulnerabilities. 6. Conduct regular audits of device configurations and permissions to ensure adherence to the principle of least privilege. 7. Prepare incident response plans that include scenarios involving denial of service on critical connectivity modules.
