CVE-2025-26432 is a vulnerability identified in Google Android version 15 that allows an attacker to cause a persistent local denial of service (DoS) on the device. The root cause of this vulnerability is a missing length check in multiple locations within the Android operating system, classified under CWE-130 (Improper Handling of Length Parameter). This flaw enables an attacker with local access and low privileges to trigger a DoS condition without requiring any user interaction. The vulnerability does not affect confidentiality or integrity but impacts availability by causing the device to become unresponsive or crash persistently. Exploitation requires local access and low privileges, meaning an attacker must have some level of access to the device but does not need elevated permissions or user involvement to execute the attack. The CVSS v3.1 base score is 5.5, indicating a medium severity level, with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H, reflecting local attack vector, low attack complexity, low privileges required, no user interaction, unchanged scope, no impact on confidentiality or integrity, and high impact on availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability's persistent nature means that once exploited, the device may remain in a DoS state until rebooted or repaired, potentially disrupting normal operations significantly.

For European organizations, this vulnerability poses a risk primarily to mobile devices running Android 15, which are widely used across enterprises and by employees for business communications and operations. A persistent local DoS could disrupt critical mobile applications, communication channels, and access to corporate resources, especially in sectors relying heavily on mobile connectivity such as finance, healthcare, and public services. Although the attack requires local access, the widespread use of Android devices in Europe means that insider threats or compromised devices could be leveraged to exploit this vulnerability. The lack of required user interaction lowers the barrier for exploitation once local access is obtained. This could lead to operational disruptions, loss of productivity, and potential impacts on service availability. While confidentiality and integrity are not directly affected, the availability impact could indirectly affect business continuity and incident response capabilities. Organizations with Bring Your Own Device (BYOD) policies or mobile device management (MDM) systems should be particularly vigilant, as affected devices could be used as attack vectors or become unusable, complicating mobile workforce management.

To mitigate this vulnerability, European organizations should prioritize the following actions: 1) Monitor for official security advisories and patches from Google and Android device manufacturers, and apply updates promptly once available. 2) Implement strict access controls and device usage policies to limit local access to Android devices, reducing the risk of exploitation by unauthorized users. 3) Employ mobile device management (MDM) solutions to enforce security configurations, detect anomalous device behavior indicative of DoS conditions, and remotely isolate or remediate affected devices. 4) Educate employees about the risks of local device access and encourage secure handling of mobile devices to prevent unauthorized physical or logical access. 5) Consider deploying endpoint detection and response (EDR) tools capable of monitoring for signs of persistent DoS or abnormal system crashes on mobile devices. 6) For critical environments, evaluate the feasibility of restricting Android 15 device usage until patches are available or alternative secure devices are deployed. 7) Establish incident response procedures specifically addressing mobile device DoS scenarios to minimize downtime and restore availability quickly.
