CVE-2025-48583 is a vulnerability identified in Google Android operating system versions 14, 15, and 16, specifically within multiple functions of the BaseBundle.java component. The root cause is a logic error that enables an attacker to execute arbitrary code locally. This flaw allows an attacker with limited privileges to escalate their privileges without requiring any additional execution privileges or user interaction, making exploitation straightforward once local access is obtained. The vulnerability impacts confidentiality, integrity, and availability, as arbitrary code execution can lead to full system compromise. The CVSS v3.1 score of 7.8 reflects high severity, with an attack vector classified as local (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), and no user interaction (UI:N). The scope remains unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Although no known exploits are currently reported in the wild, the vulnerability's characteristics suggest it could be leveraged by malicious actors to gain unauthorized control over affected devices. The affected component, BaseBundle.java, is a core part of Android's system framework, which handles key data structures and inter-process communication, making this vulnerability critical for system security. The vulnerability was reserved in May 2025 and published in December 2025, indicating a relatively recent discovery and disclosure.

The impact of CVE-2025-48583 is significant for organizations globally that rely on Android devices, including smartphones, tablets, and embedded systems. Successful exploitation allows attackers to elevate privileges locally, potentially gaining root or system-level access. This can lead to unauthorized access to sensitive data, installation of persistent malware, disruption of device functionality, and bypassing of security controls. Enterprises using Android devices for corporate communications, mobile workforce, or IoT deployments face risks of data breaches, espionage, and operational disruptions. The lack of need for user interaction lowers the barrier for exploitation, increasing the threat level. Although exploitation requires local access, attackers can leverage other vulnerabilities or social engineering to gain initial footholds. The widespread adoption of Android, especially versions 14 to 16, means a large attack surface exists. The absence of known exploits in the wild currently provides a window for mitigation, but the vulnerability remains a critical concern for security teams.

To mitigate CVE-2025-48583 effectively, organizations should prioritize the following actions: 1) Monitor Google’s official security advisories and apply patches immediately once they are released for Android versions 14, 15, and 16. 2) Implement strict access controls to limit local access to devices, including enforcing strong authentication and physical security measures. 3) Employ mobile device management (MDM) solutions to enforce security policies, restrict installation of untrusted applications, and monitor device behavior for anomalies. 4) Conduct regular security audits and vulnerability assessments on Android devices within the organization to detect potential exploitation attempts. 5) Educate users about the risks of granting local access or installing untrusted software that could facilitate exploitation. 6) Where possible, upgrade devices to newer Android versions that are not affected by this vulnerability. 7) Use runtime application self-protection (RASP) and endpoint detection and response (EDR) tools tailored for mobile environments to detect and respond to suspicious activities. These measures go beyond generic advice by focusing on controlling local access vectors and proactive monitoring until patches are available and deployed.
