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 application improperly handles permissions, allowing an attacker to leak contacts from the work profile. This leakage occurs without requiring additional execution privileges or user interaction, making it a local elevation of privilege vulnerability. The work profile is designed to separate personal and corporate data on Android devices, and unauthorized access to this data compromises confidentiality and potentially integrity. The vulnerability's CVSS 3.1 score of 7.8 reflects its high severity, with impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). The attack vector is local (AV:L), requiring low attack complexity (AC:L) and low privileges (PR:L), but no user interaction (UI:N). Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk to environments where Android devices are used for work purposes, especially in enterprise and BYOD scenarios. The lack of available patches at the time of publication necessitates proactive mitigation strategies.

For European organizations, this vulnerability threatens the confidentiality of sensitive corporate contact information stored in Android work profiles. Unauthorized access could lead to data leakage, espionage, or further lateral movement within corporate networks. The integrity of contact data could be compromised, potentially disrupting communication channels. Availability impacts arise if exploitation leads to denial of service or system instability. Organizations relying heavily on Android devices for enterprise mobility, especially those with integrated work profiles, face increased risk. The vulnerability could undermine trust in mobile device management (MDM) solutions and complicate compliance with data protection regulations such as GDPR, given the potential exposure of personal and corporate data. The local nature of the exploit means attackers need physical or local access, but the absence of user interaction requirements lowers the barrier for exploitation by malicious insiders or compromised apps.

Organizations should prioritize updating Android devices to patched versions once available from Google. Until patches are released, restrict local access to devices, enforce strong device lock policies, and limit installation of untrusted applications that could exploit this vulnerability. Employ mobile device management (MDM) solutions to enforce strict separation between personal and work profiles and monitor for anomalous access patterns to contact data. Educate users about the risks of installing unknown apps and the importance of device security. Consider disabling or limiting work profile features if not essential. Regularly audit device configurations and permissions related to contact access. Implement endpoint detection and response (EDR) tools capable of identifying suspicious local privilege escalation attempts. Coordinate with vendors and security teams to stay informed about patch releases and emerging exploit reports.
