CVE-2025-48552 is a vulnerability identified in the DevicePolicyManagerService component of Google Android, specifically within the saveGlobalProxyLocked method in DevicePolicyManagerService.java. The flaw is due to a logic error that causes a desynchronization between the in-memory state and persistent storage, leading to inconsistent device policy states. This inconsistency can be exploited by a local attacker with limited privileges to escalate their privileges without requiring additional execution rights or user interaction. The vulnerability affects Android versions 13, 14, 15, and 16, which cover a wide range of modern devices. The CVSS v3.1 base score is 7.8, indicating high severity, with attack vector local (AV:L), low attack complexity (AC:L), low privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits have been reported in the wild, the vulnerability presents a significant risk due to the potential for privilege escalation on devices that could allow attackers to gain unauthorized control over device functions and data. The flaw's presence in a core Android service that manages device policies means exploitation could undermine security controls, potentially allowing attackers to bypass restrictions or install persistent malicious configurations.

The impact of CVE-2025-48552 is substantial for organizations and individuals relying on affected Android devices. Successful exploitation allows a local attacker to escalate privileges, potentially gaining administrative control over the device. This can lead to unauthorized access to sensitive data, modification or deletion of critical system files, and disruption of device availability. For enterprises, this could mean compromise of corporate mobile devices, leading to data breaches, loss of intellectual property, or lateral movement within corporate networks. The lack of need for user interaction increases the risk of stealthy exploitation, especially on devices with multiple users or shared access. Given the widespread use of Android globally, the vulnerability could affect millions of devices, including smartphones, tablets, and embedded systems running these Android versions. The potential for high confidentiality, integrity, and availability impact makes this a critical concern for sectors such as finance, healthcare, government, and telecommunications, where mobile device security is paramount.

To mitigate CVE-2025-48552, organizations and users should apply official security patches from Google or device manufacturers as soon as they become available. Until patches are deployed, restricting physical and local access to devices is critical to prevent exploitation by unauthorized users. Implementing strong device access controls such as biometric authentication, PINs, and device encryption can reduce the risk of local attackers gaining initial access. Monitoring device logs and behavior for signs of privilege escalation or unusual policy changes can help detect exploitation attempts. Enterprises should consider deploying mobile device management (MDM) solutions that can enforce security policies and remotely manage devices to quickly respond to incidents. Additionally, educating users about the risks of installing untrusted applications or granting unnecessary permissions can reduce the attack surface. For high-security environments, isolating critical devices and limiting local user accounts can further reduce exposure.
