CVE-2025-48583 is a security vulnerability identified in Google Android operating system versions 14, 15, and 16. The root cause is a logic error in multiple functions within the BaseBundle.java component, which is part of Android's core framework responsible for managing key-value pairs and data bundles used extensively by apps and system services. This flaw allows an attacker with local access to execute arbitrary code by exploiting the logic error, leading to an elevation of privilege on the device. Notably, the exploit does not require the attacker to have any additional execution privileges beforehand, nor does it require any user interaction, making it particularly dangerous in scenarios where an attacker already has limited local access, such as through a compromised app or physical access. The vulnerability is classified as a local privilege escalation, which can be leveraged to bypass security restrictions, gain higher system privileges, and potentially execute malicious payloads with elevated rights. Although no public exploits are known at this time, the vulnerability's presence in widely deployed Android versions means it could be targeted in the future. The absence of a CVSS score indicates that the vulnerability is newly published and pending detailed scoring, but the technical details suggest a significant risk due to the ease of exploitation and impact on device security.

For European organizations, this vulnerability poses a significant risk to the security of Android devices used by employees and within enterprise environments. Successful exploitation could allow attackers to gain elevated privileges on affected devices, potentially leading to unauthorized access to sensitive corporate data, bypassing of security controls, and persistence within the device. This could facilitate further lateral movement within corporate networks, data exfiltration, or deployment of malware. Given the widespread use of Android smartphones and tablets in Europe, including in sectors such as finance, government, and critical infrastructure, the impact could be substantial. The vulnerability could also undermine trust in mobile device security, affecting bring-your-own-device (BYOD) policies and mobile workforce security. Additionally, the lack of required user interaction increases the risk of silent compromise, making detection and prevention more challenging. The impact extends to privacy concerns for individuals and organizations, as elevated privileges may allow access to personal and business communications, credentials, and other sensitive information.

To mitigate this vulnerability, organizations should prioritize the following actions: 1) Monitor for and promptly apply official security patches from Google or device manufacturers as soon as they become available for Android versions 14, 15, and 16. 2) Implement strict application control policies to limit the installation of untrusted or unnecessary apps that could exploit local vulnerabilities. 3) Employ mobile device management (MDM) solutions to enforce security policies, monitor device behavior, and restrict privilege escalation attempts. 4) Use runtime protection tools that can detect anomalous behavior indicative of privilege escalation or code injection on Android devices. 5) Educate users about the risks of sideloading apps and the importance of installing updates promptly. 6) For high-security environments, consider restricting physical access to devices and enforcing strong authentication mechanisms to reduce the likelihood of local exploitation. 7) Conduct regular security audits and vulnerability assessments on mobile devices to identify potential exploitation attempts. These measures, combined with timely patching, will reduce the risk posed by this vulnerability.
