CVE-2025-26456 is a vulnerability identified in Google Android versions 14 and 15, specifically within multiple functions of the DexUseManagerLocal.java component. The issue arises from a logic error in the code that manages the DexUseManagerLocal functionality, which is part of the Android system server processes. Exploitation of this vulnerability can cause the system server to crash, resulting in a local permanent denial of service (DoS) condition. Notably, the attack does not require any additional execution privileges, meaning that a local user without elevated permissions can trigger the vulnerability. Furthermore, no user interaction is necessary for exploitation, which increases the risk since the attack can be automated or triggered silently. The system server is a critical component of the Android operating system responsible for managing core system services; its failure leads to significant disruption of device functionality, potentially requiring a device reboot or more drastic recovery measures. Although no known exploits are currently reported in the wild, the vulnerability's nature and ease of exploitation make it a significant concern for affected devices. The absence of a CVSS score indicates that the vulnerability is newly published and may not yet have undergone full severity assessment, but the technical details suggest a serious impact on availability.

For European organizations, the impact of CVE-2025-26456 can be substantial, especially for those relying on Android devices for critical business operations, mobile workforce management, or customer-facing applications. The vulnerability can cause affected devices to become unresponsive or require frequent reboots, leading to operational disruptions, loss of productivity, and potential data loss if the device state is compromised during crashes. In sectors such as finance, healthcare, and public services where Android devices are used for secure communications or data access, this DoS vulnerability could hinder service delivery and damage organizational reputation. Additionally, organizations with Bring Your Own Device (BYOD) policies may face increased risk as the vulnerability can be exploited by local users without elevated privileges, potentially by malicious insiders or through compromised apps. The lack of required user interaction means that automated attacks or malware could trigger the DoS condition silently, increasing the threat surface. While the vulnerability does not directly compromise confidentiality or integrity, the availability impact alone can have cascading effects on business continuity and incident response capabilities.

To mitigate CVE-2025-26456, European organizations should prioritize the following actions: 1) Apply official patches or updates from Google as soon as they become available for Android versions 14 and 15. Since no patch links are currently provided, organizations should monitor Google's security advisories closely. 2) Implement device management policies that restrict installation of untrusted or unnecessary applications, reducing the risk of local exploitation. 3) Enforce strict access controls on Android devices, including limiting physical access and employing strong authentication mechanisms to prevent unauthorized local users from triggering the vulnerability. 4) Utilize Mobile Device Management (MDM) solutions to monitor device health and detect abnormal system server crashes or reboots, enabling rapid incident response. 5) Educate users about the importance of timely updates and the risks associated with local device manipulation. 6) For critical environments, consider deploying Android devices with hardened configurations or alternative OS versions not affected by this vulnerability until patches are available. 7) Conduct regular security assessments and penetration testing focused on local privilege escalation and DoS scenarios to identify potential exploitation paths related to this vulnerability.
