CVE-2025-48583 is a vulnerability identified in Google Android versions 14, 15, and 16, specifically within multiple functions of the BaseBundle.java component. The flaw is a logic error that permits arbitrary code execution locally, effectively enabling an attacker to elevate their privileges without needing additional execution privileges or user interaction. BaseBundle.java is a core part of Android's framework responsible for managing key-value pairs and data bundles passed between components, making this vulnerability critical as it can be leveraged to manipulate system behavior or escalate privileges. The attack vector is local, meaning the attacker must have some form of local access to the device, but no user interaction is required, which increases the risk of stealthy exploitation. The vulnerability affects confidentiality, integrity, and availability, as arbitrary code execution can lead to data leakage, unauthorized modifications, or denial of service. The CVSS v3.1 score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) indicates a high-severity issue with low attack complexity, requiring low privileges but no user interaction. Although no exploits have been observed in the wild yet, the potential for exploitation is significant given the widespread use of Android devices. The lack of available patches at the time of disclosure necessitates immediate attention to mitigation strategies. This vulnerability is particularly concerning for environments where Android devices are used to access sensitive corporate resources or handle confidential information.

For European organizations, the impact of CVE-2025-48583 can be substantial. Many enterprises rely on Android devices for mobile workforce productivity, secure communications, and access to corporate networks. Successful exploitation could allow attackers to gain elevated privileges on compromised devices, leading to unauthorized access to sensitive data, manipulation of applications, or disruption of services. This could result in data breaches, intellectual property theft, or operational downtime. The vulnerability’s ability to affect confidentiality, integrity, and availability simultaneously raises the risk profile for sectors such as finance, healthcare, government, and critical infrastructure. Additionally, given the local attack vector, insider threats or attackers who gain physical or remote local access to devices pose a significant risk. The absence of user interaction requirement means that exploitation can be automated or executed stealthily, increasing the likelihood of undetected compromise. The widespread use of Android in Europe, combined with the high severity of this vulnerability, underscores the need for rapid response to mitigate potential impacts.

1. Monitor for and restrict local access to Android devices, especially in sensitive environments, to reduce the risk of local exploitation. 2. Implement strict device management policies using Mobile Device Management (MDM) solutions to enforce security configurations and limit privilege escalation opportunities. 3. Apply patches and security updates promptly once Google releases fixes for the affected Android versions (14, 15, and 16). 4. Employ application whitelisting and runtime protection tools to detect and prevent unauthorized code execution on devices. 5. Educate users and administrators about the risks of local privilege escalation and the importance of physical device security. 6. Use endpoint detection and response (EDR) solutions capable of identifying suspicious activities indicative of privilege escalation attempts. 7. Limit the installation of untrusted applications and enforce the principle of least privilege on user accounts and apps. 8. Regularly audit device configurations and installed software to identify potential vulnerabilities or misconfigurations that could facilitate exploitation.
