CVE-2025-26423 is a vulnerability identified in the Android operating system, specifically affecting versions 13, 14, and 15. The flaw exists in the validateIpConfiguration function within WifiConfigurationUtil.java. The vulnerability arises due to a missing bounds check, which can be exploited to trigger a permanent denial of service (DoS) condition. This DoS leads to a local elevation of privilege without requiring any additional execution privileges or user interaction. The vulnerability is classified under CWE-400, which relates to uncontrolled resource consumption, indicating that the flaw can cause resource exhaustion or system instability. The attack vector is local (AV:L), meaning the attacker must have local access to the device, but no privileges (PR:N) or user interaction (UI:N) are required. The impact is primarily on availability (A:H), with no direct impact on confidentiality or integrity. The vulnerability could allow an attacker to disrupt device functionality permanently, potentially requiring a device reboot or factory reset to recover. Since Android is widely used across Europe on mobile devices, this vulnerability poses a risk to users and organizations relying on affected Android versions, especially in environments where device availability is critical.

For European organizations, the impact of CVE-2025-26423 could be significant in sectors where mobile device availability and reliability are essential, such as healthcare, finance, and critical infrastructure. A permanent DoS on Android devices could disrupt communication, access to enterprise applications, and operational continuity. Since exploitation does not require user interaction or elevated privileges, insider threats or malware with local access could trigger the vulnerability, increasing risk. The disruption could affect employees using Android devices for work, potentially leading to productivity loss and operational delays. Additionally, organizations with Bring Your Own Device (BYOD) policies might face challenges in managing and securing affected devices. Although no known exploits are currently in the wild, the medium severity score and ease of exploitation suggest that attackers could develop exploits, increasing future risk.

To mitigate CVE-2025-26423, European organizations should prioritize updating Android devices to patched versions as soon as Google releases fixes. Until patches are available, organizations should implement strict access controls to limit local access to devices, including enforcing strong device lock mechanisms and restricting physical access. Mobile Device Management (MDM) solutions should be used to monitor device health and detect abnormal behavior indicative of DoS conditions. Network segmentation and limiting Wi-Fi configuration changes to trusted users can reduce attack surface. Educating users about the risks of granting local access to untrusted applications or individuals is also important. For critical environments, consider deploying endpoint protection solutions capable of detecting exploitation attempts or anomalous resource consumption patterns. Regular audits of device firmware and OS versions will help ensure compliance with security policies.
