CVE-2025-22419 is a vulnerability affecting Google Android operating system versions 13, 14, and 15. It arises from multiple locations within the system where an attacker can leverage tapjacking or overlay attacks to deceive users into enabling malicious phone call forwarding. Tapjacking involves placing an invisible or misleading overlay on the screen that intercepts user taps, causing the user to unknowingly perform actions they did not intend. In this case, the attacker exploits this technique to manipulate the phone’s call forwarding settings, potentially redirecting calls to malicious numbers controlled by the attacker. The attack requires the attacker to have local execution privileges at the user level and necessitates user interaction, meaning the user must tap or interact with the device during the attack. The vulnerability is classified as an elevation of privilege because it allows an attacker to escalate their capabilities beyond what their current user permissions allow, potentially gaining unauthorized control over call forwarding features. The CVSS v3.1 base score is 7.3 (high severity), reflecting the significant impact on confidentiality, integrity, and availability if exploited. The vulnerability is tracked under CWE-1021, which pertains to improper restriction of operations within the bounds of a user interface, indicating a failure to properly restrict user interface interactions that can be exploited. Although no known exploits are currently reported in the wild, the vulnerability poses a serious risk due to the sensitive nature of call forwarding and the potential for abuse in intercepting or redirecting communications. No official patches have been linked yet, so mitigation currently relies on user awareness and limiting exposure to untrusted applications or links that could trigger the attack.

The impact of CVE-2025-22419 is significant for organizations and individual users relying on Android devices for communication. Successful exploitation can lead to unauthorized call forwarding, enabling attackers to intercept, redirect, or manipulate phone calls, which compromises confidentiality and privacy. This can facilitate further attacks such as social engineering, fraud, or espionage. The integrity of call settings is compromised, potentially allowing attackers to alter device behavior without user consent. Availability can also be affected if call forwarding disrupts normal telephony services. For organizations, especially those with mobile workforces or sensitive communications, this vulnerability could lead to data leaks, unauthorized access to voice communications, and reputational damage. The requirement for user interaction limits automated exploitation but does not eliminate risk, as social engineering can be used to trick users. The lack of known exploits in the wild suggests the vulnerability is not yet actively exploited, but the high severity score indicates it should be treated as a priority once patches are available.

1. Monitor official Google Android security bulletins for patches addressing CVE-2025-22419 and apply them promptly once released. 2. Educate users about the risks of tapjacking and overlay attacks, emphasizing caution when interacting with unexpected prompts or applications requesting permissions related to call settings. 3. Restrict installation of applications from untrusted sources or unknown developers to reduce exposure to malicious apps that could leverage this vulnerability. 4. Employ mobile device management (MDM) solutions to enforce security policies that limit the ability to install or run potentially harmful applications and to monitor call forwarding settings for unauthorized changes. 5. Encourage users to verify call forwarding settings regularly and report any unexpected changes immediately. 6. Implement runtime protections or overlay detection mechanisms where possible to prevent or alert on suspicious overlay activity. 7. For organizations, consider network-level monitoring for unusual call forwarding patterns or anomalies in telephony usage that could indicate exploitation attempts. These steps go beyond generic advice by focusing on user education, proactive monitoring, and leveraging enterprise controls to reduce risk until patches are available.
