CVE-2025-26424 is a vulnerability identified in Google Android version 15, specifically within multiple functions of the VpnManager.java component. The root cause is a logic error that leads to a cross-user data leak, allowing local information disclosure without requiring any additional execution privileges or user interaction. This means that an attacker with local access to the device can exploit this flaw to access sensitive data belonging to other users on the same device. The vulnerability arises from improper handling of user context or permissions within the VPN management code, which fails to adequately isolate data between different user profiles or sessions. Since no elevated privileges or user actions are needed, exploitation is straightforward for any local user or process with basic access. Although no known exploits are currently reported in the wild, the vulnerability’s nature suggests it could be leveraged to compromise confidentiality by exposing private information across user boundaries on affected Android devices. The absence of a CVSS score indicates this is a newly published issue, and detailed impact metrics are not yet available. However, the technical details confirm it is a local information disclosure vulnerability with a broad scope within Android 15’s VPN management subsystem.

For European organizations, the impact of CVE-2025-26424 could be significant, especially in environments where Android devices are used in multi-user scenarios or where sensitive corporate data is accessed via VPNs on Android 15 devices. Information disclosure vulnerabilities can lead to leakage of confidential corporate information, user credentials, or other sensitive data, potentially facilitating further attacks such as identity theft, corporate espionage, or lateral movement within networks. Since the vulnerability does not require elevated privileges or user interaction, it lowers the barrier for exploitation by malicious insiders or compromised applications with local access. This risk is heightened in sectors with strict data privacy regulations such as GDPR, where unauthorized data exposure can lead to regulatory penalties and reputational damage. Additionally, organizations relying on Android devices for remote work or secure communications may find their VPN data integrity and confidentiality compromised, undermining trust in their security posture.

To mitigate CVE-2025-26424, European organizations should prioritize updating all Android 15 devices to the latest security patches as soon as Google releases a fix. Until a patch is available, organizations should enforce strict device access controls to limit local user access, including disabling multi-user profiles on sensitive devices or restricting device sharing. Employ Mobile Device Management (MDM) solutions to monitor and control VPN configurations and usage, ensuring that only trusted applications and users can access VPN services. Additionally, organizations should audit VPN-related logs for unusual access patterns that might indicate exploitation attempts. Where possible, implement application sandboxing and privilege separation to minimize the impact of local exploits. User education on device security and the risks of local access should also be reinforced. Finally, consider deploying endpoint detection and response (EDR) tools capable of detecting anomalous local activity related to VPN management components.
