CVE-2025-36902 is a vulnerability identified in the Android kernel, specifically within the syna_cdev_ioctl_store_pid() function of the syna_tcm2_sysfs.c component. The flaw is a heap-based buffer overflow that results in an out-of-bounds write. This vulnerability can be exploited locally to achieve an elevation of privilege, allowing an attacker to gain System execution privileges on the affected device. The vulnerability requires that the attacker already have high privileges (PR:H) on the device, but does not require any user interaction (UI:N) to exploit. The vulnerability impacts confidentiality, integrity, and availability, as it allows an attacker to execute arbitrary code with elevated privileges, potentially leading to full system compromise. The CVSS v3.1 base score is 6.7, categorized as medium severity, reflecting the need for existing high privileges to exploit and the local attack vector. The vulnerability is classified under CWE-122 (Heap-based Buffer Overflow), which is a common and dangerous class of memory corruption bugs. No known exploits in the wild have been reported as of the publication date, and no official patches have been linked yet. This vulnerability affects the Android kernel, which is a core component of the Android operating system used widely in mobile devices globally.

For European organizations, the impact of CVE-2025-36902 can be significant, especially for enterprises relying on Android devices for business operations, including mobile workforce management, secure communications, and access to corporate resources. Successful exploitation could allow an attacker with existing high privileges on an Android device to escalate to system-level control, potentially bypassing security controls, accessing sensitive corporate data, installing persistent malware, or disrupting device availability. This could lead to data breaches, loss of intellectual property, and operational disruptions. Given the widespread use of Android devices in Europe across various sectors such as finance, healthcare, government, and critical infrastructure, the vulnerability poses a risk to the confidentiality, integrity, and availability of sensitive information and services. The lack of required user interaction increases the risk of automated or stealthy exploitation once an attacker gains initial access. However, the requirement for system-level privileges to initiate the exploit limits the attack surface to scenarios where an attacker already has some foothold on the device.

To mitigate CVE-2025-36902, European organizations should prioritize the following actions: 1) Monitor for and promptly apply security updates from Google and device manufacturers once patches become available, as this vulnerability resides in the Android kernel and requires vendor-supplied fixes. 2) Enforce strict device management policies using Mobile Device Management (MDM) solutions to restrict installation of untrusted applications and reduce the risk of privilege escalation. 3) Implement application whitelisting and privilege separation on Android devices to limit the ability of applications to gain high privileges. 4) Conduct regular security audits and vulnerability assessments on Android devices used within the organization to detect signs of compromise or exploitation attempts. 5) Educate users and administrators about the risks of privilege escalation vulnerabilities and the importance of maintaining updated devices. 6) Employ runtime protection and behavior monitoring tools on Android devices to detect anomalous activities indicative of exploitation attempts. 7) Limit physical and network access to devices to reduce opportunities for attackers to gain initial high privileges necessary to exploit this vulnerability.
