CVE-2025-32345 is a vulnerability identified in Google Android versions 15 and 16, specifically within the updateState method of the ContentProtectionTogglePreferenceController.java component. The flaw is a logic error that permits a secondary user on the device to disable the primary user's deceptive app scanning setting. This setting is designed to protect users by scanning for potentially deceptive or malicious applications. The vulnerability enables a local attacker with limited privileges (secondary user) to escalate their privileges without needing additional execution rights or any user interaction. The root cause is improper access control logic that fails to adequately separate user privilege boundaries in a multi-user environment. The vulnerability is classified under CWE-269 (Improper Privilege Management), indicating a failure to enforce correct privilege levels. The CVSS v3.1 base score is 7.8, reflecting a high severity due to the vulnerability's impact on confidentiality, integrity, and availability, combined with low attack complexity and no requirement for user interaction. Although no public exploits have been reported, the flaw could be leveraged to disable security features, potentially allowing further malicious activity or unauthorized access on affected devices. The vulnerability affects Android versions 15 and 16, which are widely deployed in consumer and enterprise environments. The issue was publicly disclosed on September 4, 2025, and as of this report, no patches have been linked, emphasizing the need for prompt remediation once available.

The vulnerability allows a secondary user on an Android device to disable the primary user's deceptive app scanning setting, which undermines the device's security posture by potentially allowing deceptive or malicious apps to operate undetected. This local privilege escalation can compromise the confidentiality of user data by enabling unauthorized access or manipulation. Integrity is affected as attackers can alter security settings without authorization, and availability may be impacted if malicious apps disrupt device operations. The flaw is particularly concerning in shared device scenarios, such as family tablets, enterprise devices with multiple user profiles, or kiosks. Exploitation does not require user interaction, increasing the risk of silent compromise. Organizations relying on Android devices for sensitive operations may face increased risk of data breaches, unauthorized access, and potential lateral movement within networks. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits following disclosure.

Organizations and users should monitor official Google Android security advisories for patches addressing CVE-2025-32345 and apply updates promptly once available. Until patches are released, limiting the creation of secondary user accounts on sensitive devices can reduce exposure. Employ strict user account management policies, ensuring secondary users have minimal privileges and are monitored for suspicious activity. Use mobile device management (MDM) solutions to enforce security configurations and restrict changes to security-related settings. Regularly audit device configurations to detect unauthorized modifications to deceptive app scanning or similar security features. Educate users about the risks of multi-user environments and encourage the use of personal devices for sensitive tasks. For enterprise deployments, consider isolating critical applications and data within secure containers or virtual environments to limit the impact of privilege escalation. Finally, implement comprehensive endpoint detection and response (EDR) tools capable of identifying anomalous behavior indicative of privilege escalation attempts.
