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, a scenario where the kernel reads the same data twice without proper synchronization, potentially leading to inconsistent or maliciously manipulated data being processed. This race condition can be exploited locally to escalate privileges without requiring any prior elevated permissions or user interaction, making it a significant security concern. The vulnerability allows an attacker with local access to the device to execute code or perform actions with higher privileges than intended, potentially compromising the confidentiality, integrity, and availability of the system. Although no public exploits have been reported yet, the nature of the flaw and its location in the kernel suggest that exploitation could be reliable and impactful. The Android kernel is a core component of the operating system, and vulnerabilities here can affect a wide range of devices, including smartphones, tablets, and embedded systems. The absence of a CVSS score indicates that the vulnerability is newly disclosed and pending further assessment. The race condition and double fetch issues are well-known vectors for privilege escalation, often exploited to bypass security controls. This vulnerability underscores the importance of timely patching and kernel security hardening in Android devices.

For European organizations, the impact of CVE-2025-36916 could be substantial. Android devices are ubiquitous in both personal and professional environments across Europe, often used to access corporate networks, sensitive data, and critical applications. An attacker exploiting this vulnerability could gain elevated privileges on a compromised device, enabling them to install persistent malware, exfiltrate data, or pivot into enterprise networks. This could lead to breaches of personal data protected under GDPR, intellectual property theft, and disruption of business operations. The fact that no user interaction is required lowers the barrier for exploitation, increasing the risk. Organizations with Bring Your Own Device (BYOD) policies or those deploying Android-based IoT devices are particularly vulnerable. The kernel-level nature of the vulnerability means that traditional application-layer security controls may be insufficient to detect or prevent exploitation. Additionally, the lack of known exploits in the wild currently provides a window for proactive defense, but also means that attackers could develop exploits rapidly once the vulnerability is public knowledge. The impact extends to sectors such as finance, healthcare, government, and critical infrastructure, where Android devices are integrated into operational workflows.

Given the absence of an official patch link, organizations should prioritize monitoring for updates from Google and device manufacturers to apply security patches promptly once available. In the interim, organizations should enforce strict device usage policies, limiting local access to Android devices and employing mobile device management (MDM) solutions to enforce security configurations and detect anomalous behavior. Employing kernel integrity monitoring and leveraging security frameworks like SELinux on Android can help mitigate exploitation risks. Regularly auditing device logs for signs of privilege escalation attempts and restricting installation of untrusted applications can reduce attack surface. For high-risk environments, consider isolating critical Android devices from sensitive networks or using hardened Android builds with reduced kernel attack surfaces. User education on the risks of local device compromise and enforcing strong authentication mechanisms can further reduce the likelihood of successful exploitation. Collaboration with vendors to expedite patch deployment and sharing threat intelligence within industry groups will enhance collective defense.
