CVE-2025-48620 is a vulnerability identified in the VoiceInteractionManagerService.java component of Google Android operating system versions 13 through 16. The flaw stems from a logic error in the onSomePackagesChanged method, which manages package changes such as app installations and uninstallations. Specifically, when a third-party application is uninstalled, its component name can erroneously persist within the VoiceInteractionManagerService due to improper cleanup of internal state. This persistence can be leveraged by a local attacker who has limited privileges on the device to escalate their privileges without needing additional execution rights or user interaction. The vulnerability affects confidentiality, integrity, and availability by potentially allowing unauthorized access to sensitive system functions or data and could enable further malicious activities on the device. The attack vector is local, requiring the attacker to have some level of access to the device, but no user interaction is necessary, increasing the risk of stealthy exploitation. Although no known exploits are currently reported in the wild, the vulnerability's characteristics and CVSS score of 7.8 indicate a significant risk. The flaw highlights the importance of secure state management in system services that interact with third-party applications and the need for rigorous validation and cleanup procedures during app lifecycle events.

For European organizations, this vulnerability poses a significant risk, especially those with employees using Android devices for work purposes or organizations that deploy Android-based mobile solutions. Exploitation could lead to unauthorized privilege escalation on devices, potentially allowing attackers to access sensitive corporate data, bypass security controls, or install persistent malicious software. This could compromise confidentiality and integrity of corporate information and disrupt availability of mobile services. The lack of required user interaction makes it easier for attackers to exploit the vulnerability silently. Organizations in sectors such as finance, government, healthcare, and critical infrastructure, where mobile device security is paramount, could face increased risks of data breaches or operational disruptions. Additionally, the widespread use of Android in Europe means that the attack surface is large, necessitating proactive mitigation to prevent exploitation.

Organizations should monitor for official patches from Google and apply them promptly once available to remediate the vulnerability. Until patches are deployed, implementing strict mobile device management (MDM) policies can reduce risk by limiting installation of untrusted third-party applications and enforcing least privilege principles on user devices. Regular audits of installed applications and their permissions can help detect suspicious persistence behaviors. Employing endpoint detection and response (EDR) solutions capable of monitoring for anomalous privilege escalations on Android devices can provide early warning of exploitation attempts. Educating users about the risks of installing unverified apps and encouraging use of official app stores can reduce exposure. For high-risk environments, consider isolating sensitive mobile workloads or using containerization to limit the impact of potential exploits. Finally, organizations should maintain an inventory of Android devices and their OS versions to prioritize patching efforts effectively.
