CVE-2025-36916 is a vulnerability identified in the Android kernel, specifically within the PrepareWorkloadBuffers function of the gxp_main_actor.cc source file. The flaw arises from a race condition that causes a double fetch, categorized under CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization). This race condition can be exploited locally to escalate privileges without needing additional execution privileges or user interaction. The vulnerability allows an attacker with low privileges on the device to manipulate kernel memory or state, potentially gaining higher privileges and full control over the device. The attack vector is local, requiring the attacker to have some form of access to the device, but no user interaction is necessary, increasing the risk of automated or stealthy exploitation. The CVSS v3.1 score of 7.0 indicates a high severity, with the vector string AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H reflecting local attack vector, high attack complexity, low privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability. No public exploits or patches are currently available, but the vulnerability has been publicly disclosed as of December 11, 2025. This vulnerability could be leveraged by malicious actors to compromise Android devices, potentially affecting a wide range of users and organizations relying on Android-based systems.

For European organizations, this vulnerability poses a significant risk due to the widespread use of Android devices in both consumer and enterprise environments. Successful exploitation could lead to unauthorized access to sensitive corporate data, disruption of mobile services, and potential lateral movement within corporate networks if Android devices are used as entry points. The high impact on confidentiality, integrity, and availability means that critical business applications and communications could be compromised. Sectors such as finance, healthcare, government, and critical infrastructure, which often rely on mobile devices for secure communications and operations, are particularly vulnerable. Additionally, the lack of required user interaction means that attacks could be automated or executed silently, increasing the threat level. The vulnerability could also undermine trust in mobile device security, affecting compliance with data protection regulations such as GDPR if personal data is exposed or manipulated.

Organizations should prioritize applying official patches from Google or device manufacturers as soon as they become available. Until patches are released, limiting local access to devices is critical; this includes enforcing strong physical security controls and restricting access to device debugging or developer modes. Employ mobile device management (MDM) solutions to enforce security policies, monitor device behavior for anomalies, and restrict installation of untrusted applications that could exploit this vulnerability. Regularly update Android devices to the latest security versions and educate users about the risks of granting unnecessary permissions or installing unknown software. Network segmentation can help contain potential compromises originating from mobile devices. Additionally, organizations should monitor security advisories and threat intelligence feeds for any emerging exploit activity related to this vulnerability to respond promptly.
