CVE-2025-0089 is a high-severity elevation of privilege vulnerability affecting multiple recent versions of the Google Android operating system, specifically versions 13, 14, and 15. The vulnerability arises from a logic error in the Launcher app code, which is a core component responsible for managing the home screen and launching applications. Due to this flaw, an attacker with limited privileges on the device can hijack the Launcher app without requiring any additional execution privileges or user interaction. This means that exploitation can occur silently and autonomously once the attacker has local access to the device. The vulnerability is classified under CWE-693, which relates to protection mechanism failures, indicating that the Launcher app fails to properly enforce security controls that prevent privilege escalation. The CVSS v3.1 base score is 7.8, reflecting high severity with impacts on confidentiality, integrity, and availability (all rated high). The attack vector is local (AV:L), requiring low attack complexity (AC:L) and low privileges (PR:L), but no user interaction (UI:N). The scope is unchanged (S:U), meaning the vulnerability affects the same security scope. Although no known exploits are currently reported in the wild, the ease of exploitation and the critical nature of the Launcher app make this a significant threat. The absence of a patch link suggests that a fix may not yet be publicly available or is pending release. Organizations relying on Android devices, especially those running affected versions, should consider this vulnerability a serious risk to device security and data protection.

For European organizations, the impact of CVE-2025-0089 can be substantial. Since the vulnerability allows local privilege escalation without user interaction, an attacker who gains any form of local access—such as through a compromised app, physical access, or another lower-privilege exploit—can escalate privileges to gain control over the Launcher app. This can lead to unauthorized access to sensitive data, manipulation of the user interface, installation of persistent malware, or disruption of device availability. In sectors with high reliance on Android devices for business operations, such as finance, healthcare, and government, this could result in data breaches, loss of user trust, and regulatory non-compliance under GDPR. The stealthy nature of the exploit increases the risk of undetected compromise. Additionally, given the widespread use of Android devices in Europe, including in BYOD (Bring Your Own Device) environments, the vulnerability could be exploited to pivot attacks into corporate networks. The lack of required user interaction further exacerbates the threat, as typical user awareness or training will not mitigate the risk.

To mitigate CVE-2025-0089 effectively, European organizations should: 1) Prioritize updating Android devices to patched versions as soon as Google releases a fix. Until then, restrict local access to devices by enforcing strong physical security controls and device lock policies. 2) Implement Mobile Device Management (MDM) solutions to monitor device integrity, enforce security policies, and remotely wipe or quarantine compromised devices. 3) Limit installation of third-party apps to trusted sources only, reducing the risk of initial local compromise that could lead to privilege escalation. 4) Employ application whitelisting and sandboxing techniques to isolate the Launcher app and prevent unauthorized modifications. 5) Conduct regular security audits and penetration tests focusing on mobile endpoints to detect potential exploitation attempts. 6) Educate users about the importance of device security, emphasizing the risks of granting unnecessary permissions or connecting to untrusted networks. 7) Monitor for unusual device behavior indicative of privilege escalation, such as unexpected app launches or system modifications. These steps go beyond generic advice by focusing on controlling local access vectors and enhancing detection capabilities specific to this vulnerability.
