CVE-2025-48632 is a vulnerability in Google Android affecting versions 14, 15, and 16, specifically in the setDisplayName method of the AssociationRequest.java component. The issue stems from improper input validation that allows CDM (Content Decryption Module) associations to persist after a user has disassociated them. This persistence can be exploited by a local attacker to escalate privileges on the device without requiring additional execution privileges or user interaction. The vulnerability is classified under CWE-20 (Improper Input Validation), indicating that the root cause is failure to properly validate or sanitize input data. The CVSS v3.1 base score of 7.8 reflects a high severity, with attack vector being local (AV:L), low attack complexity (AC:L), requiring low privileges (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 public exploits are known at this time, the vulnerability could allow attackers who have limited local access to gain elevated privileges, potentially compromising sensitive data, modifying system settings, or disrupting device availability. The lack of user interaction requirement increases the risk of automated or stealthy exploitation in environments where local access is possible. The vulnerability affects multiple recent Android versions, which are widely deployed globally, including across Europe. The absence of patch links suggests that fixes may still be pending or in development, emphasizing the need for vigilance and interim mitigations.

For European organizations, the impact of CVE-2025-48632 can be significant, especially for those relying heavily on Android devices for business operations, mobile workforce, or critical infrastructure management. Successful exploitation can lead to unauthorized access to sensitive information, modification or deletion of data, and disruption of device functionality. This could compromise corporate data confidentiality and integrity, potentially leading to data breaches or operational downtime. The local attack vector means that attackers need some form of local access, which could be achieved through physical access, compromised user accounts, or malware already present on the device. Given the high Android market penetration in Europe, including in sectors such as finance, healthcare, and government, the vulnerability poses a risk to both private and public sector entities. Additionally, the persistence of CDM associations could affect digital rights management and content security, impacting media and communication services. The lack of user interaction requirement increases the risk of automated exploitation in environments where devices are shared or less physically secure. Overall, the vulnerability could facilitate lateral movement and privilege escalation within corporate networks, amplifying its potential damage.

1. Monitor and restrict local access to Android devices, ensuring that only trusted users have physical or local access. 2. Implement strict device management policies using Mobile Device Management (MDM) solutions to enforce security configurations and detect anomalous privilege escalations. 3. Limit installation of untrusted applications and regularly audit installed apps to reduce the risk of malware that could leverage this vulnerability. 4. Apply principle of least privilege to user accounts on Android devices to minimize the impact of local privilege escalation. 5. Monitor system logs and security events for unusual behavior indicative of privilege escalation attempts. 6. Stay informed about official patches or updates from Google and apply them promptly once available. 7. Consider deploying endpoint detection and response (EDR) tools capable of detecting suspicious local privilege escalation activities on Android devices. 8. Educate users about the risks of leaving devices unattended or accessible to unauthorized individuals. 9. For organizations with critical Android-based infrastructure, consider network segmentation to limit the spread of potential compromises. 10. Engage with vendors and security communities to track developments and share threat intelligence related to this vulnerability.
