CVE-2025-48589 is a vulnerability identified in multiple functions within the HeaderPrivacyIconsController.kt file of Google Android versions 13 through 16. The root cause is a logic error that improperly manages permission grants across users, enabling a local attacker with limited privileges to escalate their access rights without requiring additional execution privileges or user interaction. This flaw allows an attacker to bypass normal permission checks, potentially granting themselves elevated capabilities that compromise system confidentiality, integrity, and availability. The vulnerability is exploitable locally, meaning an attacker must have some level of access to the device but does not need to trick the user or gain further execution rights. The CVSS v3.1 base score is 7.8, reflecting high severity due to the significant impact on core security properties and the relatively low complexity of exploitation. Although no exploits have been reported in the wild yet, the vulnerability's nature makes it a critical concern for Android users and administrators. The absence of a patch link indicates that a fix may still be pending or in development, emphasizing the need for vigilance and interim protective measures. This vulnerability affects a broad range of Android versions, including the latest releases, increasing the scope of potentially impacted devices globally.

For European organizations, this vulnerability poses a significant risk, especially those relying heavily on Android devices for business operations, mobile workforce, or BYOD policies. Successful exploitation could allow attackers to gain unauthorized access to sensitive corporate data, manipulate system settings, or disrupt device availability. This could lead to data breaches, loss of intellectual property, or operational downtime. The lack of user interaction requirement increases the risk of stealthy attacks, making detection more difficult. Industries with stringent data protection requirements, such as finance, healthcare, and government sectors, are particularly vulnerable. The widespread use of Android in Europe, combined with the high severity of this flaw, means that organizations must act swiftly to mitigate potential impacts. Failure to address this vulnerability could also lead to regulatory compliance issues under GDPR if personal data is compromised.

1. Limit local access to Android devices by enforcing strong physical security controls and restricting device usage to trusted personnel only. 2. Implement mobile device management (MDM) solutions to monitor and control device permissions and detect unusual privilege escalations. 3. Apply principle of least privilege for all user accounts on Android devices to minimize the potential impact of exploitation. 4. Monitor system logs and security alerts for signs of unauthorized permission changes or suspicious activities related to HeaderPrivacyIconsController.kt or related components. 5. Stay informed about official patches or security updates from Google and prioritize their deployment as soon as they become available. 6. Educate users about the risks of local device access and encourage reporting of lost or stolen devices immediately. 7. Consider temporary use of additional endpoint protection tools that can detect privilege escalation attempts until a patch is deployed.
