CVE-2025-36887 is a high-severity vulnerability affecting the Android kernel, specifically within the function wl_cfgscan_update_v3_schedscan_results() located in the wl_cfgscan.c source file. The vulnerability arises due to an incorrect bounds check that can lead to an out-of-bounds write, classified under CWE-787 (Out-of-bounds Write). This flaw allows a local attacker to escalate privileges on the affected device without requiring any additional execution privileges or user interaction. The vulnerability is exploitable locally, meaning an attacker must have some level of access to the device but does not need to trick the user into performing any action. The CVSS v3.1 base score is 7.8, indicating a high severity, with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. This means the attack requires local access with low complexity and low privileges but no user interaction, and it can lead to a complete compromise of confidentiality, integrity, and availability of the system. The vulnerability impacts the Android kernel, which is a critical component responsible for managing hardware and system resources. An out-of-bounds write in this context can corrupt kernel memory, potentially allowing an attacker to execute arbitrary code with kernel privileges, bypass security controls, and gain full control over the device. No known exploits are currently reported in the wild, and no patches are linked yet, indicating that the vulnerability is newly disclosed and may require urgent attention from device manufacturers and users. Given the kernel-level nature of the flaw, exploitation could lead to persistent and stealthy compromises, making it a significant threat to Android devices.

For European organizations, this vulnerability poses a substantial risk, especially those relying heavily on Android devices for business operations, including mobile workforce management, secure communications, and access to corporate resources. Successful exploitation could allow attackers to gain root-level access on devices, leading to data breaches, unauthorized access to sensitive corporate information, and potential lateral movement within enterprise networks if devices are connected to internal systems. The compromise of Android devices could also undermine multi-factor authentication mechanisms, expose confidential communications, and facilitate the deployment of malware or ransomware. Given the widespread use of Android smartphones and tablets across Europe, including in sectors such as finance, healthcare, government, and critical infrastructure, the impact could be broad and severe. Additionally, the lack of required user interaction lowers the barrier for exploitation, increasing the risk of automated or stealthy attacks within organizational environments. The vulnerability could also affect consumer devices used by employees, increasing the attack surface for supply chain and indirect attacks on enterprises.

To mitigate this vulnerability effectively, European organizations should: 1) Prioritize updating Android devices as soon as official patches become available from Google or device manufacturers. Engage with vendors to confirm patch timelines and deployment plans. 2) Implement strict device management policies using Mobile Device Management (MDM) solutions to enforce timely OS updates and restrict installation of untrusted applications. 3) Limit local access to devices by enforcing strong authentication mechanisms such as biometrics or PINs and restricting physical access to authorized personnel only. 4) Monitor devices for unusual behavior indicative of kernel-level compromise, including unexpected privilege escalations or system instability. 5) Educate users on the importance of device security and discourage the use of rooted or jailbroken devices, which could increase vulnerability exposure. 6) Employ network segmentation and zero-trust principles to minimize the impact of compromised devices on corporate networks. 7) Prepare incident response plans that include procedures for handling compromised mobile devices, including forensic analysis and device isolation. These steps go beyond generic advice by focusing on proactive patch management, access control, behavioral monitoring, and organizational policies tailored to the specific risks posed by kernel-level Android vulnerabilities.
