CVE-2025-36924 is a security vulnerability identified in the Android kernel, specifically within the function ss_DecodeLcsAssistDataReqMsg located in the ss_LcsManagement.c source file. The vulnerability arises from an incorrect bounds check that can lead to an out-of-bounds write operation. This type of memory corruption flaw can be exploited by an attacker in close physical proximity (proximal or adjacent) to the target device, enabling them to escalate their privileges on the device without needing any prior execution privileges or user interaction. The vulnerability is significant because it affects the Android kernel, a critical component responsible for managing hardware and system resources. Exploiting this flaw could allow attackers to gain elevated privileges, potentially leading to full device compromise, unauthorized access to sensitive data, or disruption of device functionality. Although no known exploits have been reported in the wild as of the publication date, the nature of the vulnerability suggests it could be leveraged in targeted attacks, especially in environments where attackers can be physically near the victim device. The lack of a CVSS score indicates that the vulnerability is newly disclosed, and detailed impact metrics are not yet available. However, the technical details and attack vector imply a high risk due to the ease of exploitation and the critical nature of the affected component.

For European organizations, this vulnerability poses a significant risk, particularly for those relying heavily on Android devices for business operations, communications, or data storage. Successful exploitation could lead to unauthorized privilege escalation, enabling attackers to bypass security controls, access sensitive corporate data, or deploy further malware. This could disrupt business continuity, compromise intellectual property, and violate data protection regulations such as GDPR. The proximity-based attack vector means that attackers need to be physically near the target device, which could be feasible in public spaces, offices, or during travel. Organizations with employees frequently working in shared or public environments are at higher risk. Additionally, sectors such as finance, government, healthcare, and critical infrastructure, which often use Android devices for secure communications and operations, could face heightened threats. The absence of known exploits currently provides a window for proactive mitigation, but the potential impact on confidentiality, integrity, and availability is substantial if exploited.

Organizations should prioritize monitoring for updates and patches from Google addressing this vulnerability and apply them immediately upon release. In the interim, restricting physical proximity access to sensitive devices can reduce risk, including enforcing strict access controls in workplaces and public areas. Network segmentation and the use of VPNs can help limit exposure to local network attacks. Device management policies should enforce the use of up-to-date security configurations and restrict installation of untrusted applications that could facilitate exploitation. Security teams should implement anomaly detection to identify unusual privilege escalations or kernel-level activity on Android devices. Employee awareness training about the risks of physical proximity attacks and the importance of device security can further reduce exposure. For high-risk environments, consider deploying endpoint detection and response (EDR) solutions capable of monitoring kernel-level events on Android devices. Finally, organizations should prepare incident response plans specific to mobile device compromises to ensure rapid containment and remediation.
