CVE-2025-48537 is a high-severity vulnerability affecting multiple recent versions of the Google Android operating system, specifically versions 13 through 16. The vulnerability arises from improper input validation in multiple locations within the Android OS, which can be exploited locally to cause a persistent denial of service (DoS) condition on the device. This DoS can lead to local information disclosure without requiring any additional execution privileges or user interaction. The vulnerability is classified under CWE-20, indicating that it stems from improper input validation. The CVSS 3.1 base score is 7.1, reflecting a high severity level with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H. This means the attack requires local access with low complexity and low privileges but no user interaction, and it impacts confidentiality (high) and availability (high) but not integrity. The scope remains unchanged. Although no known exploits are currently reported in the wild, the vulnerability's characteristics make it a significant risk for local attackers who can access the device. The persistent DoS could render the device unusable until reboot or further remediation, and the information disclosure could expose sensitive data stored locally on the device. Given Android's widespread use in mobile devices, this vulnerability could affect a broad user base, especially in environments where local access to devices is possible, such as enterprise or governmental settings.

For European organizations, this vulnerability poses a notable risk, especially for those relying heavily on Android devices for business operations, including mobile workforce management, secure communications, and data access. The persistent DoS can disrupt critical business functions by rendering devices inoperable, potentially leading to operational downtime and productivity loss. The local information disclosure aspect could expose sensitive corporate or personal data stored on the device, increasing the risk of data breaches and compliance violations under regulations like GDPR. Since exploitation does not require user interaction and only low privileges, insider threats or attackers with physical or local network access could leverage this vulnerability. This is particularly concerning for sectors with high security requirements such as finance, healthcare, and government agencies. The lack of known exploits in the wild currently provides a window for proactive mitigation, but the vulnerability's presence in multiple recent Android versions means a large attack surface remains.

To mitigate CVE-2025-48537 effectively, European organizations should prioritize the following actions: 1) Deploy patches and updates from Google as soon as they become available, as no patch links are currently provided, indicating the need for vigilance on official update channels. 2) Implement strict device access controls to limit local access to authorized personnel only, reducing the risk of local exploitation. 3) Employ mobile device management (MDM) solutions to monitor device health and detect abnormal behavior indicative of DoS conditions or information leakage. 4) Educate users about the risks of local device access and enforce policies against unauthorized physical access. 5) For high-risk environments, consider additional endpoint security solutions that can detect and block suspicious local activities. 6) Regularly audit and review device configurations and installed applications to minimize attack vectors. 7) Prepare incident response plans specifically addressing mobile device compromise scenarios to ensure rapid containment and recovery.
