CVE-2025-36887 is a local privilege escalation vulnerability found in the Android kernel, specifically within the function wl_cfgscan_update_v3_schedscan_results() in the wl_cfgscan.c source file. The vulnerability arises due to an incorrect bounds check that leads to a possible out-of-bounds write. This type of memory corruption can allow an attacker to overwrite adjacent memory locations, potentially modifying kernel data structures or code pointers. Exploiting this flaw enables an attacker with local access to escalate their privileges without requiring any additional execution privileges or user interaction. Since the vulnerability exists in the kernel, successful exploitation could allow an attacker to gain root or system-level privileges, bypassing Android's security model and sandboxing mechanisms. The vulnerability does not require the attacker to have any special permissions beyond local code execution, which means any app or process running on the device could potentially exploit this flaw to elevate privileges. No known exploits are currently reported in the wild, and no CVSS score has been assigned yet. However, the nature of the vulnerability—an out-of-bounds write in the kernel—makes it a serious security risk that could be leveraged to compromise the confidentiality, integrity, and availability of affected devices.

For European organizations, this vulnerability poses a significant risk, especially for enterprises relying on Android devices for sensitive communications, mobile workforce operations, or IoT deployments. An attacker exploiting this flaw could gain root access on affected devices, allowing them to install persistent malware, exfiltrate sensitive data, or disrupt device functionality. This could lead to data breaches, loss of intellectual property, and operational disruptions. Given the widespread use of Android devices across Europe in both consumer and enterprise environments, the vulnerability could be exploited in targeted attacks against corporate employees or supply chain partners. Additionally, sectors such as finance, healthcare, and government, which often use Android devices for secure communications and mobile applications, could face elevated risks. The lack of user interaction requirement increases the threat level, as exploitation can occur silently without alerting the user. The vulnerability also threatens the integrity of device security controls, potentially enabling attackers to bypass security policies and protections enforced by the Android OS.

European organizations should prioritize the following mitigation steps: 1) Monitor for official patches or security updates from Google and device manufacturers and deploy them promptly to all Android devices in use. 2) Implement strict device management policies using Mobile Device Management (MDM) solutions to enforce timely updates and restrict installation of untrusted applications. 3) Limit local access to devices by enforcing strong authentication and physical security controls to reduce the risk of local exploitation. 4) Employ runtime protection and behavior monitoring tools on Android devices to detect anomalous activities indicative of privilege escalation attempts. 5) Educate users about the risks of installing untrusted apps or granting unnecessary permissions, even though user interaction is not required for this exploit, to reduce the attack surface. 6) For critical environments, consider network segmentation and restricting device connectivity to minimize potential lateral movement if a device is compromised. 7) Maintain an inventory of all Android devices and their OS/kernel versions to identify and prioritize vulnerable assets for patching.
