CVE-2025-48527 is a security vulnerability identified in multiple versions of the Google Android operating system, specifically versions 13 through 16. The flaw arises from a logic error in the handling of work profile notifications, which are designed to separate personal and work-related data on the same device. Due to this logic error, hidden notifications intended for the work profile can be leaked, resulting in local information disclosure. This vulnerability does not require any additional execution privileges, meaning that an attacker with local access to the device can exploit the flaw without needing elevated permissions. Furthermore, exploitation does not require any user interaction, such as clicking or opening a notification, which increases the risk of silent data leakage. The vulnerability is limited to information disclosure and does not directly enable code execution or privilege escalation. No known exploits are currently reported in the wild, and no patches or fixes have been linked yet. The affected Android versions cover a broad range of recent releases, indicating that a significant portion of Android devices in use could be vulnerable if not updated promptly. The nature of the flaw suggests that sensitive information from work profiles, which may include confidential corporate communications or data, could be exposed to unauthorized users who have local access to the device, such as through physical access or compromised user accounts.

For European organizations, this vulnerability poses a significant risk to data confidentiality, particularly for enterprises that utilize Android's work profile feature to segregate corporate data from personal data on employee devices. The leakage of hidden work profile notifications could expose sensitive business information, including emails, messages, or alerts related to corporate applications. This exposure could lead to information leakage that undermines corporate privacy policies and regulatory compliance, such as GDPR, which mandates strict controls over personal and corporate data. Since exploitation requires only local access and no user interaction, insider threats or attackers who gain physical access to devices could leverage this vulnerability to extract sensitive information without detection. The impact is especially critical for sectors with high data sensitivity, such as finance, healthcare, and government agencies operating in Europe. Additionally, the lack of a patch at the time of publication means organizations must rely on interim mitigations to protect their data. The vulnerability does not affect device availability or integrity directly but compromises confidentiality, which can have downstream effects on trust and regulatory compliance.

To mitigate the risk posed by CVE-2025-48527, European organizations should implement the following specific measures: 1) Enforce strict physical security controls to limit unauthorized local access to devices, including secure storage and device lock policies. 2) Apply device management policies that restrict or monitor the use of work profiles, ensuring that only trusted applications and users have access. 3) Utilize Mobile Device Management (MDM) or Enterprise Mobility Management (EMM) solutions to monitor notification behavior and detect anomalous access patterns related to work profile notifications. 4) Educate employees about the importance of device security and the risks of leaving devices unattended or unlocked. 5) Monitor for updates from Google and prioritize patch deployment as soon as a fix becomes available. 6) Consider disabling work profiles temporarily on devices that handle highly sensitive information until the vulnerability is addressed. 7) Implement additional encryption or containerization solutions for sensitive corporate data to reduce the impact of notification leaks. These measures go beyond generic advice by focusing on controlling local access, monitoring notification flows, and managing work profile usage.
