CVE-2025-48627 is a vulnerability identified in the Android operating system, specifically affecting versions 13 and 14. The flaw exists in the startNextMatchingActivity method within the ActivityTaskManagerService.java component, which is responsible for managing activity launches. Due to a logic error, it is possible for an attacker with local access and limited privileges to launch an activity from the background without requiring user interaction or additional execution privileges. This behavior constitutes an elevation of privilege vulnerability, as it allows an attacker to bypass normal restrictions on activity launches, potentially gaining higher privileges on the device. The vulnerability impacts confidentiality, integrity, and availability, as an attacker could execute unauthorized actions, access sensitive data, or disrupt device functionality. The CVSS score of 7.8 reflects the high severity, with attack vector local, low attack complexity, low privileges required, no user interaction, and high impact on all security properties. Although no known exploits are currently reported in the wild, the vulnerability's nature makes it a significant risk, especially in environments where Android devices are used for sensitive or critical operations. The absence of patch links indicates that fixes may not yet be publicly available, emphasizing the need for proactive mitigation strategies.

For European organizations, this vulnerability poses a substantial risk due to the widespread use of Android devices in corporate environments, including smartphones and tablets used for communication, data access, and operational control. Exploitation could allow attackers to escalate privileges locally, potentially leading to unauthorized access to corporate data, installation of malicious applications, or disruption of device operations. This is particularly critical for sectors relying heavily on mobile security, such as finance, healthcare, and government agencies. The ability to exploit without user interaction increases the risk of stealthy attacks that can evade detection. Additionally, the impact on confidentiality, integrity, and availability could lead to data breaches, loss of trust, regulatory penalties under GDPR, and operational downtime. Organizations with Bring Your Own Device (BYOD) policies may face increased exposure if personal devices are compromised and connected to corporate networks.

1. Restrict installation of applications from untrusted sources to reduce the risk of local attackers gaining initial access. 2. Implement strict mobile device management (MDM) policies to control app permissions and monitor for unusual activity related to activity launches. 3. Encourage users to avoid installing unnecessary or unverified applications that could exploit this vulnerability. 4. Monitor device logs for suspicious background activity that could indicate exploitation attempts. 5. Once patches or updates are released by Google, prioritize their deployment across all affected Android devices. 6. Employ endpoint detection and response (EDR) solutions capable of detecting privilege escalation behaviors on mobile devices. 7. Educate users about the risks of privilege escalation vulnerabilities and the importance of device security hygiene. 8. Consider network segmentation and limiting sensitive data access from mobile devices until the vulnerability is mitigated.
