CVE-2025-48586 is a vulnerability identified in Google Android versions 15 and 16, specifically within the onActivityResult method of the EditFdnContactScreen.java component. The flaw is categorized as a confused deputy problem (CWE-441), where the system component improperly handles requests, leading to unintended information disclosure. In this case, the vulnerability allows an attacker to leak contacts from the work profile, which is intended to be isolated from the personal profile for security and privacy reasons. The attack vector is local, meaning the attacker must have some level of local access but does not require additional execution privileges or user interaction to exploit the flaw. The vulnerability enables an elevation of privilege by bypassing normal access controls, potentially granting the attacker access to sensitive contact information and possibly further system privileges. The CVSS v3.1 base score is 7.8, reflecting high severity due to the high impact on confidentiality, integrity, and availability, combined with low attack complexity and no need for user interaction. Although no public exploits are currently known, the vulnerability represents a significant risk given the widespread use of Android and the sensitive nature of work profile data. The flaw underscores the challenges in securely managing inter-profile communication and enforcing strict access controls within mobile operating systems.

The vulnerability allows local attackers to escalate privileges without requiring additional permissions or user interaction, potentially exposing sensitive contact information from the work profile. This breach of confidentiality can lead to privacy violations, corporate espionage, or targeted attacks leveraging leaked contact data. Integrity and availability impacts arise if the attacker uses elevated privileges to modify or disrupt system components or data. Organizations relying on Android devices for work profile separation risk data leakage between personal and corporate environments, undermining security policies and compliance requirements. The flaw could facilitate lateral movement within devices or networks if combined with other exploits. Given the prevalence of Android devices globally, the potential impact is widespread, affecting enterprise users, government agencies, and individuals who use work profiles for secure data segregation. The absence of required user interaction increases the likelihood of silent exploitation, making detection and response more challenging.

Until official patches are released, organizations should enforce strict app permission policies, especially limiting access to contacts and inter-profile communication. Employ mobile device management (MDM) solutions to monitor and restrict local app behaviors that could exploit this vulnerability. Disable or limit the use of work profiles on devices where not essential, reducing the attack surface. Encourage users to avoid installing untrusted or unnecessary applications that could leverage local access to exploit the flaw. Implement enhanced logging and anomaly detection focused on inter-profile data access attempts. Once patches become available, prioritize immediate deployment on all affected Android devices. Additionally, review and harden the configuration of Android Enterprise features to ensure robust separation between personal and work profiles. Security teams should also educate users about the risks of local privilege escalation and maintain updated incident response plans for mobile threats.
