CVE-2025-36924 is a vulnerability identified in the Android kernel's location services management code, specifically within the function ss_DecodeLcsAssistDataReqMsg in the ss_LcsManagement.c source file. The root cause is an incorrect bounds check that allows an out-of-bounds write, classified under CWE-120 (Classic Buffer Overflow) and CWE-787 (Out-of-bounds Write). This flaw enables an attacker in close proximity or on the same network segment to remotely trigger an elevation of privilege without requiring any user interaction or additional execution privileges. The vulnerability affects the Android kernel, a critical component responsible for core system operations and security enforcement. The CVSS v3.1 base score is 8.0, indicating high severity, with attack vector as adjacent network (AV:A), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and impacting confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits have been reported yet, the nature of the vulnerability suggests that an attacker could leverage it to gain kernel-level privileges, potentially leading to full device compromise, data theft, or persistent malware installation. The vulnerability was reserved in April 2025 and published in December 2025, with no patch links currently available, indicating that mitigation efforts may still be underway or pending deployment.

The impact of CVE-2025-36924 is substantial for organizations and individuals using Android devices, especially those relying on the kernel's security guarantees. Exploitation could allow attackers to escalate privileges from a limited user or network position to full kernel-level control, bypassing security mechanisms and potentially installing persistent malware or stealing sensitive data. This could affect mobile devices used in corporate environments, government agencies, and critical infrastructure sectors, leading to data breaches, espionage, or disruption of services. The vulnerability's remote exploitability without user interaction increases the risk of widespread attacks, particularly in environments where attackers can gain network proximity, such as public Wi-Fi, enterprise networks, or cellular networks. The absence of known exploits currently provides a window for proactive defense, but the high severity and kernel-level impact necessitate urgent attention to prevent exploitation.

Organizations should prioritize monitoring for updates from Google and Android device manufacturers, applying security patches as soon as they become available. In the interim, network segmentation and restricting access to sensitive Android devices can reduce exposure to adjacent network attackers. Employing mobile device management (MDM) solutions to enforce security policies and restrict installation of untrusted applications can limit attack vectors. Additionally, disabling or restricting location services or related features that invoke the vulnerable code path may reduce risk temporarily. Security teams should enhance network monitoring for unusual activity indicative of exploitation attempts, such as anomalous privilege escalations or kernel-level anomalies. Collaboration with vendors to expedite patch development and deployment is critical. Finally, educating users about the risks of connecting to untrusted networks can help mitigate exposure.
