CVE-2025-36890 is an elevation of privilege vulnerability identified in the Android kernel, the core component of the Android operating system responsible for managing hardware and system resources. Elevation of privilege vulnerabilities allow an attacker with limited access to escalate their privileges to gain higher-level permissions, potentially enabling them to execute arbitrary code with kernel-level privileges. This can lead to full system compromise, bypassing security controls, and unauthorized access to sensitive data or system functions. Although specific technical details such as the exact kernel subsystem or exploit vector are not provided, the vulnerability's presence in the kernel implies a critical security risk because the kernel operates at the highest privilege level. The absence of a CVSS score and known exploits in the wild suggests this vulnerability is newly disclosed and may not yet be actively exploited, but the potential for exploitation remains significant given the nature of kernel privilege escalation. Android devices running affected kernel versions are at risk, which includes a wide range of smartphones, tablets, and other devices using the Android OS. The vulnerability was reserved in April 2025 and published in September 2025, indicating a recent discovery and disclosure timeline.

For European organizations, the impact of CVE-2025-36890 could be substantial, especially for enterprises relying on Android devices for business operations, mobile workforce management, or IoT deployments. Successful exploitation could allow attackers to gain unauthorized root access on devices, leading to data breaches, installation of persistent malware, or lateral movement within corporate networks. This could compromise confidentiality, integrity, and availability of sensitive corporate data and services. Additionally, organizations in sectors with high regulatory requirements such as finance, healthcare, and critical infrastructure could face compliance violations and reputational damage if devices are compromised. The widespread use of Android devices in Europe means that many organizations could be affected, particularly if patching is delayed or devices are no longer supported by vendors. The lack of known exploits currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits following public disclosure.

Given the kernel-level nature of this vulnerability, mitigation should focus on timely patching and system updates. Organizations should: 1) Monitor official Google and device vendor security advisories for patches addressing CVE-2025-36890 and apply them promptly to all affected Android devices. 2) Implement mobile device management (MDM) solutions to enforce update policies and ensure devices are running secure firmware versions. 3) Restrict installation of untrusted applications and enforce least privilege principles on Android devices to reduce the attack surface. 4) Employ runtime protection mechanisms such as SELinux enforcing mode and verified boot to limit the impact of potential exploits. 5) Conduct regular security audits and vulnerability assessments on mobile infrastructure. 6) Educate users about the risks of privilege escalation attacks and encourage cautious behavior regarding app permissions and downloads. Since no patches are currently linked, organizations should prioritize risk assessment and prepare for rapid deployment once patches become available.
