CVE-2025-36905 is a vulnerability identified in the Android kernel's gxp_mapping_create function within the gxp_mapping.c source file. The root cause is a logic error that improperly handles privilege checks, enabling a local attacker with limited privileges to escalate their rights on the device. Notably, exploitation does not require the attacker to have any additional execution privileges or user interaction, making it easier to leverage once local access is obtained. The vulnerability is classified under CWE-693, which relates to protection mechanism failures due to logic errors. The CVSS v3.1 base score of 7.8 reflects a high severity, with metrics indicating local attack vector (AV:L), low attack complexity (AC:L), low privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits have been reported yet, the flaw could be exploited by malicious local applications or attackers who gain limited access to the device, potentially leading to full system compromise. The affected product is the Android kernel, which is integral to all Android devices, making this a widespread concern. The vulnerability was reserved in April 2025 and published in September 2025, with no patches currently linked, indicating that mitigation efforts are pending. Given the critical role of the kernel in enforcing security boundaries, this vulnerability poses a significant risk if left unpatched.

The impact of CVE-2025-36905 is substantial for organizations and individuals using Android devices. Successful exploitation allows an attacker to escalate privileges locally, potentially gaining root or system-level access. This can lead to unauthorized access to sensitive data, installation of persistent malware, bypassing of security controls, and disruption of device availability. For enterprises, compromised Android devices can serve as entry points into corporate networks, especially in Bring Your Own Device (BYOD) environments. The lack of required user interaction and low complexity of exploitation increase the likelihood of attacks once local access is achieved, such as through malicious apps or physical device access. The vulnerability affects confidentiality, integrity, and availability, making it a critical concern for sectors relying heavily on mobile security, including finance, healthcare, government, and telecommunications. The widespread use of Android globally amplifies the potential scale of impact, with millions of devices at risk until patches are deployed.

To mitigate CVE-2025-36905, organizations and users should: 1) Monitor for official security updates from Google and device manufacturers and apply kernel patches promptly once available. 2) Restrict local access to devices by enforcing strong authentication and limiting physical access to trusted personnel only. 3) Employ mobile device management (MDM) solutions to control app installations and detect suspicious local privilege escalation attempts. 4) Use security frameworks like SELinux enforcing mode to limit the impact of potential exploits. 5) Regularly audit installed applications and remove those from untrusted sources to reduce the risk of malicious local code execution. 6) Educate users about the risks of sideloading apps and encourage use of official app stores. 7) For organizations, implement network segmentation and endpoint detection to identify compromised devices early. 8) Consider deploying runtime protection tools that can detect anomalous kernel-level behavior. These steps go beyond generic advice by focusing on controlling local access vectors and preparing for rapid patch deployment.
