CVE-2025-36908 is a vulnerability identified in the Android kernel, specifically within the function lwis_top_register_io in the source file lwis_device_top.c. The flaw arises due to an incorrect bounds check that can lead to an out-of-bounds write, a classic example of CWE-787 (Out-of-bounds Write). This vulnerability allows a local attacker with system execution privileges to escalate their privileges further within the system. Notably, exploitation does not require any user interaction, which increases the risk of automated or stealthy attacks. The vulnerability requires the attacker to have some level of existing privileges (PR:H - High privileges), but once exploited, it can compromise confidentiality, integrity, and availability of the affected Android device by allowing arbitrary code execution or kernel memory corruption. The CVSS v3.1 base score is 6.7, indicating a medium severity level, with high impact on confidentiality, integrity, and availability. Since this vulnerability is in the kernel, it affects all Android devices running the vulnerable kernel versions, potentially impacting a wide range of devices including smartphones, tablets, and embedded Android systems. No known exploits are currently reported in the wild, and no patches have been linked yet, which suggests that mitigation is pending or under development. The vulnerability's presence in the kernel means it could be leveraged to bypass security mechanisms and gain persistent control over the device.

For European organizations, the impact of CVE-2025-36908 could be significant, especially for those relying heavily on Android devices for business operations, mobile workforce, or embedded Android systems in IoT and industrial applications. Successful exploitation could lead to unauthorized access to sensitive corporate data, disruption of mobile services, and potential lateral movement within corporate networks if compromised devices are connected to internal systems. The ability to escalate privileges locally without user interaction increases the risk of stealthy attacks by insiders or malware that has already gained limited access. This could undermine trust in mobile device security, lead to data breaches, and impact compliance with data protection regulations such as GDPR. Furthermore, organizations using Android-based devices in critical infrastructure or industrial control systems could face operational disruptions or sabotage. The lack of available patches at the time of disclosure means organizations must be vigilant and implement interim controls to reduce risk.

Given the absence of an official patch, European organizations should implement the following specific mitigations: 1) Restrict access to Android devices to trusted users only, minimizing the number of users with system-level privileges to reduce the attack surface. 2) Employ mobile device management (MDM) solutions to enforce strict security policies, including application whitelisting and privilege restrictions. 3) Monitor devices for unusual kernel-level activity or signs of exploitation attempts using endpoint detection and response (EDR) tools tailored for mobile platforms. 4) Disable or limit access to vulnerable kernel interfaces if possible, through configuration or kernel hardening techniques. 5) Educate users about the risks of installing untrusted applications or granting elevated permissions. 6) Prepare for rapid deployment of patches once available by maintaining an inventory of affected devices and ensuring update mechanisms are functional. 7) For critical environments, consider isolating Android devices from sensitive networks or using virtual private networks (VPNs) with strict access controls to limit potential lateral movement.
