CVE-2026-0026 is a vulnerability identified in the Android 14 operating system, specifically within the PermissionManagerServiceImpl.java component. The flaw stems from a logic error in the removePermission method, which incorrectly handles permission removal requests. This error enables an attacker with local access to override any system-level permission without requiring additional execution privileges. The vulnerability requires user interaction, such as convincing the user to perform a specific action, to trigger the exploit. The core issue relates to missing authorization checks (CWE-862), allowing unauthorized modification of system permissions. The vulnerability has a CVSS v3.1 base score of 7.8, reflecting high severity due to its impact on confidentiality, integrity, and availability. Although no public exploit code or active exploitation has been reported, the potential for privilege escalation makes this a significant threat. The flaw affects Android 14 devices, which are widely deployed globally, particularly on newer smartphones and tablets. The lack of a patch link suggests that remediation may still be pending or in progress.

If exploited, this vulnerability allows an attacker with local access and minimal privileges to escalate their rights to system-level permissions, effectively gaining full control over the device. This can lead to unauthorized access to sensitive data, modification or deletion of critical system files, installation of persistent malware, and disruption of device functionality. The compromise of confidentiality, integrity, and availability can affect personal user data, enterprise mobile environments, and any applications relying on Android's permission model. Given the widespread use of Android 14 in consumer and enterprise devices, the impact could be extensive, potentially affecting millions of users worldwide. The requirement for user interaction somewhat limits mass exploitation but does not eliminate targeted attacks, especially in scenarios involving social engineering or malicious apps.

Organizations and users should prioritize updating their Android 14 devices as soon as official patches or security updates become available from Google or device manufacturers. Until patches are released, minimizing the risk involves restricting installation of untrusted applications and avoiding interactions with suspicious prompts or links that could trigger the exploit. Employing mobile device management (MDM) solutions to enforce strict app installation policies and permission controls can reduce exposure. Security teams should monitor for unusual permission changes or privilege escalations on devices. Developers should review and harden permission management code to ensure proper authorization checks. Additionally, educating users about the risks of interacting with unknown content can help mitigate user interaction requirements for exploitation.
