CVE-2025-36918 is a vulnerability identified in the Android kernel, specifically within the aoc_service_read_message function of the aoc_ipc_core.c source file. The flaw arises from improper input validation that leads to an out-of-bounds read (CWE-125). This memory safety issue can be exploited by a local attacker who already has system execution privileges to escalate their privileges further, potentially gaining full control over the device. The vulnerability does not require user interaction, increasing its risk profile in environments where local access is possible. The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) indicates that the attack vector is local, with low attack complexity, requiring privileges but no user interaction, and results in high impact on confidentiality, integrity, and availability. The Android kernel is a critical component, and exploitation could allow attackers to bypass security mechanisms, access sensitive data, or disrupt device operations. Although no exploits have been reported in the wild yet, the vulnerability’s characteristics suggest it could be leveraged in targeted attacks or by malware to deepen system compromise. The absence of patches at the time of reporting necessitates vigilance and proactive mitigation by device manufacturers and users.

For European organizations, this vulnerability poses a significant threat, especially those relying heavily on Android devices for business operations, communication, or data storage. The ability to escalate privileges locally means that if an attacker gains limited access—through physical access, malicious apps, or other means—they could fully compromise the device. This could lead to data breaches, unauthorized access to corporate networks, and disruption of services. Sectors such as finance, government, healthcare, and critical infrastructure, which often use Android devices for secure communications or operational control, are at heightened risk. The impact extends to mobile device management (MDM) environments where compromised devices could be used as pivot points for broader network attacks. Additionally, the lack of user interaction requirement increases the risk of automated or stealthy exploitation in environments where devices are shared or less physically secure.

1. Monitor for official security advisories from Google and device manufacturers and apply patches immediately once available. 2. Restrict local access to Android devices, enforcing strong physical security controls and limiting administrative privileges. 3. Employ mobile device management solutions to enforce security policies, detect anomalous behavior, and remotely isolate or wipe compromised devices. 4. Harden devices by disabling unnecessary services and restricting installation of untrusted applications to reduce the attack surface. 5. Implement endpoint detection and response (EDR) tools capable of monitoring kernel-level activities to identify potential exploitation attempts. 6. Educate users about the risks of granting elevated permissions to apps and the importance of device security hygiene. 7. For organizations with critical Android deployments, consider additional network segmentation and multi-factor authentication to limit lateral movement post-compromise.
