CVE-2025-26422 is a security vulnerability identified in Google Android version 15, specifically within the WindowManagerService.java component. The issue arises from a missing permission check in the dump functionality of the WindowManagerService, which allows the 'dumpsys' command to be executed without the necessary permissions. Dumpsys is a diagnostic tool used to dump system service information, and improper access to it can reveal sensitive system details or allow unauthorized actions. This vulnerability enables a local attacker to escalate privileges without requiring any additional execution privileges or user interaction. The flaw is classified under CWE-279, which relates to improper authorization. The CVSS v3.1 base score is 4.0, indicating a medium severity level, with the vector AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N. This means the attack requires local access, low attack complexity, no privileges required, no user interaction, unchanged scope, and impacts confidentiality slightly without affecting integrity or availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability allows an attacker with local access to gain elevated privileges by bypassing permission checks in the WindowManagerService's dumpsys command, potentially exposing sensitive system information or enabling further local attacks.

For European organizations, this vulnerability poses a moderate risk primarily to devices running Android 15, which may include smartphones, tablets, and embedded systems used within enterprise environments. The elevation of privilege can allow a local attacker—such as an insider, a malicious app, or someone with physical access—to gain unauthorized access to system-level information or capabilities. While the impact on confidentiality is limited, it could facilitate further attacks or data leakage. The lack of required user interaction and privileges makes it easier for attackers to exploit once local access is obtained. This could be particularly concerning for organizations with Bring Your Own Device (BYOD) policies or those deploying Android devices in sensitive roles, such as field operations or secure communications. However, since the vulnerability does not affect integrity or availability, the direct impact on critical business operations may be limited unless combined with other vulnerabilities. The absence of known exploits reduces immediate risk but does not eliminate the need for vigilance and timely patching once available.

European organizations should implement the following specific mitigation steps: 1) Restrict physical and local access to Android 15 devices to trusted personnel only, minimizing the risk of local exploitation. 2) Monitor and control the installation of applications, especially those requesting system-level permissions or diagnostic capabilities, to prevent malicious apps from leveraging this vulnerability. 3) Employ Mobile Device Management (MDM) solutions to enforce security policies, including restricting access to developer or diagnostic tools like dumpsys. 4) Stay informed about official patches or updates from Google and apply them promptly once released. 5) Conduct regular security audits and penetration testing focusing on local privilege escalation vectors on Android devices. 6) Educate users about the risks of installing untrusted applications and the importance of device security hygiene. These targeted measures go beyond generic advice by focusing on controlling local access and diagnostic tool usage, which are critical given the nature of this vulnerability.
