CVE-2025-36905 is a high-severity local privilege escalation vulnerability affecting the Android kernel, specifically within the function gxp_mapping_create in the gxp_mapping.c source file. The vulnerability arises from a logic error in the code that improperly manages privilege boundaries, allowing an attacker with limited privileges to escalate their rights to a higher privilege level without requiring additional execution privileges or user interaction. This means that an attacker who already has some form of local access to an affected Android device can exploit this flaw to gain elevated privileges, potentially full kernel-level control. The vulnerability is classified under CWE-693, which relates to protection mechanism failures due to logic errors. The CVSS v3.1 base score is 7.8, indicating a high severity level, with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, meaning the attack requires local access with low complexity, privileges required are low, no user interaction is needed, and the impact on confidentiality, integrity, and availability is high. No known exploits are currently reported in the wild, and no patches have been linked yet, suggesting that mitigation may rely on vendor updates once available. The vulnerability affects the Android kernel, which is a core component of the Android operating system used widely across mobile devices globally. Exploitation could allow attackers to bypass security controls, install persistent malware, access sensitive data, or disrupt device operations.

For European organizations, this vulnerability poses a significant risk, especially those relying on Android devices for business operations, including mobile workforce, BYOD (Bring Your Own Device) policies, and IoT devices running Android-based systems. Successful exploitation could lead to unauthorized access to corporate data, compromise of authentication credentials, and installation of persistent malware that could facilitate further lateral movement within corporate networks. The high impact on confidentiality, integrity, and availability means sensitive personal and corporate information could be exposed or altered, potentially violating GDPR and other data protection regulations. Additionally, critical infrastructure sectors using Android devices for monitoring or control could face operational disruptions. The lack of required user interaction and low complexity of exploitation increase the risk of automated or stealthy attacks, making timely mitigation essential to prevent widespread compromise.

European organizations should implement a multi-layered mitigation strategy: 1) Inventory and identify all Android devices in use, including versions of the Android kernel, to assess exposure. 2) Monitor vendor communications closely for official patches or security updates from Google and device manufacturers and prioritize rapid deployment once available. 3) Until patches are released, restrict local access to devices by enforcing strong physical security controls and limiting user privileges to the minimum necessary. 4) Employ mobile device management (MDM) solutions to enforce security policies, detect anomalous behavior, and remotely wipe or quarantine compromised devices. 5) Educate users about the risks of installing untrusted applications or granting unnecessary permissions, as initial foothold is required for exploitation. 6) Consider implementing kernel integrity monitoring and exploit detection tools on critical devices to detect attempts to exploit this vulnerability. 7) Regularly audit and update security configurations and access controls to reduce the attack surface. 8) Collaborate with cybersecurity teams to prepare incident response plans specific to Android device compromise scenarios.
