CVE-2025-48600 is a vulnerability identified in Google Android versions 15 and 16 that results from missing permission checks in multiple files within the operating system. This security flaw allows an attacker with local access to the device to bypass user isolation mechanisms and disclose information belonging to other users on the same device. The vulnerability does not require any additional execution privileges, meaning that even unprivileged local users can exploit it. Furthermore, no user interaction is necessary, which increases the risk of automated or stealthy exploitation. The root cause is a failure to enforce proper permission validation when accessing certain resources or files, leading to unauthorized cross-user data exposure. Although no known exploits have been reported in the wild, the vulnerability is publicly disclosed and could be targeted by attackers seeking sensitive information. The affected Android versions, 15 and 16, represent recent releases of the operating system, which are deployed on a wide range of mobile devices globally, including in Europe. The absence of a CVSS score complicates severity assessment, but the nature of the flaw—local information disclosure without privilege escalation or user interaction—indicates a significant privacy risk. The vulnerability primarily impacts confidentiality, as unauthorized data access could expose personal or sensitive information. Integrity and availability are not directly affected. The scope is limited to devices running the specified Android versions and requires local access, which somewhat limits the attack surface but remains a concern for multi-user devices or shared environments. The vulnerability is currently in a published state, and no patches or mitigations have been linked yet, emphasizing the need for vigilance and prompt updates once fixes are released.

For European organizations, this vulnerability poses a privacy and confidentiality risk, especially for enterprises and public sector entities that use Android devices in multi-user or shared contexts. Sensitive corporate or personal data could be exposed to unauthorized local users, potentially leading to data breaches or compliance violations under regulations such as GDPR. The lack of required privileges or user interaction lowers the barrier for exploitation, increasing the threat level in environments where device access is not tightly controlled. Although the vulnerability does not directly impact system integrity or availability, the exposure of confidential information can have reputational and operational consequences. Mobile device management (MDM) policies and endpoint security controls may need to be reviewed to mitigate risks. The threat is particularly relevant for sectors with high mobile device usage and sensitive data processing, including finance, healthcare, and government agencies across Europe.

Organizations should monitor for official patches from Google and apply them promptly once available to remediate the missing permission checks. Until patches are released, restricting physical and local access to Android devices is critical to reduce exploitation risk. Implement strict device usage policies, including disabling multi-user access where not necessary and enforcing strong authentication mechanisms to limit unauthorized local access. Employ mobile device management (MDM) solutions to enforce security configurations and monitor device behavior for suspicious activity. Educate users about the risks of sharing devices and the importance of securing their devices physically and logically. Additionally, consider isolating sensitive applications or data using containerization or sandboxing techniques to minimize the impact of potential information disclosure. Regularly audit device configurations and access logs to detect any anomalous access patterns that could indicate exploitation attempts.
