CVE-2025-36930 is a vulnerability identified in the Android kernel component, specifically within the GetHostAddress function of the gxp_buffer.h source file. The root cause is a missing bounds check that allows an out-of-bounds write operation. This type of vulnerability is classified under CWE-120 (Buffer Copy without Checking Size of Input) and CWE-787 (Out-of-bounds Write). The out-of-bounds write can corrupt memory, potentially allowing a local attacker to escalate privileges on the device without requiring additional execution privileges or user interaction. The attack vector is local, meaning the attacker must have some form of access to the device, but no elevated privileges are needed initially. The vulnerability affects the Android kernel, which is a critical component responsible for managing hardware and system resources. Exploitation could lead to full system compromise, affecting confidentiality, integrity, and availability of the device. The CVSS v3.1 base score is 7.8, indicating a high severity level due to the combination of local attack vector, low attack complexity, required privileges, and no user interaction. No public exploits are currently known, but the vulnerability is publicly disclosed and should be considered a significant risk. The lack of available patches at the time of disclosure means organizations must be vigilant and prepare for rapid deployment once fixes are released.

For European organizations, the impact of CVE-2025-36930 could be substantial, especially for those relying heavily on Android devices for business operations, communications, or as part of their critical infrastructure. Successful exploitation could allow attackers to gain elevated privileges on affected devices, enabling them to bypass security controls, access sensitive information, install persistent malware, or disrupt device functionality. This could lead to data breaches, espionage, or operational disruptions. The vulnerability affects the kernel, which means a compromise could undermine the entire device security model. Organizations in sectors such as finance, healthcare, government, and telecommunications are particularly at risk due to the sensitive nature of their data and the criticality of their operations. Additionally, the lack of user interaction requirement increases the risk of automated or stealthy exploitation by insiders or malware already present on devices. The potential for widespread impact is heightened by the large market share of Android devices in Europe, making this a significant concern for enterprise mobile security.

1. Monitor official Google and Android security advisories closely for the release of patches addressing CVE-2025-36930 and apply them immediately upon availability. 2. Implement strict device management policies, including restricting installation of untrusted applications and enforcing least privilege principles on Android devices. 3. Use Mobile Device Management (MDM) solutions to enforce security configurations and remotely manage device updates. 4. Limit local access to devices by enforcing strong authentication mechanisms and physical security controls to reduce the risk of local exploitation. 5. Conduct regular security audits and vulnerability assessments on Android devices within the organization to detect signs of compromise. 6. Educate users about the risks of local privilege escalation vulnerabilities and the importance of reporting suspicious device behavior. 7. Consider network segmentation and endpoint detection solutions that can identify anomalous activities indicative of exploitation attempts. 8. For critical environments, evaluate the use of hardened or custom Android builds with additional security controls to mitigate kernel-level vulnerabilities.
