CVE-2025-26456 is a medium-severity vulnerability affecting Google Android versions 14 and 15. The flaw exists in multiple functions within the DexUseManagerLocal.java component, where a logic error can cause the system server process to crash. This results in a local permanent denial of service (DoS) condition. The vulnerability does not require any user interaction to be exploited, and no additional execution privileges are necessary beyond local access. The root cause is classified under CWE-703, which relates to improper resource management leading to DoS. Since the system server is a critical Android component responsible for managing core system services, its crash can severely disrupt device functionality, potentially requiring a device reboot or factory reset to recover. The CVSS v3.1 base score is 5.5, reflecting a medium severity level, with attack vector as local, low attack complexity, low privileges required, no user interaction, and impact limited to availability only. No known public exploits or patches are currently available, indicating that exploitation in the wild is not yet observed but the vulnerability is publicly disclosed and should be addressed promptly.

For European organizations, this vulnerability poses a risk primarily to Android devices running versions 14 and 15, which may be used by employees or within operational environments. The permanent local DoS could disrupt mobile device availability, impacting communication, access to corporate resources, and mobile-dependent workflows. In sectors relying heavily on mobile technology, such as finance, healthcare, and critical infrastructure, device unavailability could degrade operational efficiency and potentially delay critical responses. Although the vulnerability does not allow privilege escalation or data compromise, the denial of service could be leveraged by malicious insiders or malware with local access to cause persistent disruption. Given that no user interaction is required, automated or background processes could trigger the crash, increasing the risk of widespread impact on affected devices within an organization.

To mitigate this vulnerability, European organizations should prioritize updating Android devices to versions beyond 15 or applying any forthcoming security patches from Google as soon as they become available. Until patches are released, organizations should implement strict device usage policies limiting installation of untrusted applications and restrict local access to devices to trusted personnel only. Employ mobile device management (MDM) solutions to monitor device health and detect abnormal system server crashes. Additionally, organizations should educate users about the importance of reporting device instability promptly. For critical environments, consider deploying endpoint protection solutions capable of detecting anomalous behavior indicative of exploitation attempts. Network segmentation and limiting local access to devices can further reduce the risk of exploitation. Finally, maintain regular backups of critical mobile data to minimize operational impact in case of device failure.
