CVE-2025-22427 is a local elevation of privilege vulnerability affecting Google Android versions 13, 14, and 15. The flaw exists in the NotificationAccessConfirmationActivity.java component, specifically within the onCreate method. Due to a logic error, the system may grant notification access above the lock screen improperly. This means that an attacker with local access and the ability to interact with the device user interface could exploit this vulnerability to escalate privileges without needing additional execution privileges. The vulnerability requires user interaction, implying that the attacker must trick or persuade the user to perform some action to trigger the exploit. The core issue is a logic flaw that bypasses intended security controls around notification access, potentially allowing unauthorized apps or processes to gain elevated notification permissions. Although no known exploits are currently reported in the wild, the vulnerability's presence in recent Android versions used widely across devices makes it a significant concern. The lack of a CVSS score suggests that the vulnerability is newly disclosed and not yet fully assessed, but the potential for privilege escalation on a widely deployed mobile OS is noteworthy.

For European organizations, this vulnerability could have several impacts. Android devices are commonly used for corporate communication, mobile workforce productivity, and access to enterprise resources. An attacker exploiting this vulnerability could gain elevated notification access, potentially allowing them to intercept or manipulate sensitive notifications, including those related to authentication, emails, or confidential communications. This could lead to information leakage or facilitate further attacks such as social engineering or lateral movement within corporate networks. Since the vulnerability requires user interaction, phishing or social engineering campaigns could be used to trigger the exploit. The impact is particularly relevant for organizations with Bring Your Own Device (BYOD) policies or those that rely heavily on Android devices for secure communications. Additionally, the ability to bypass lock screen restrictions undermines device security, increasing the risk of unauthorized access to sensitive data. While the vulnerability does not directly allow remote code execution, the privilege escalation could be a stepping stone for more sophisticated attacks. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as threat actors may develop exploits once patches are released or the vulnerability becomes widely known.

To mitigate this vulnerability, European organizations should prioritize the following actions: 1) Ensure all Android devices are updated to the latest available security patches from Google or device manufacturers as soon as they become available, especially versions 13, 14, and 15. 2) Implement strict mobile device management (MDM) policies that enforce timely OS updates and restrict installation of untrusted applications, reducing the risk of malicious apps exploiting this flaw. 3) Educate users about the risks of interacting with unsolicited prompts or notifications, emphasizing caution with granting permissions or interacting with unexpected UI elements, particularly on the lock screen. 4) Monitor device behavior for unusual notification access requests or privilege escalations using endpoint detection and response (EDR) tools integrated with mobile device management solutions. 5) Limit the use of sensitive notifications on lock screens where possible, configuring devices to hide sensitive content until after authentication. 6) For high-security environments, consider restricting or disabling notification access permissions for non-essential apps. 7) Stay informed through official Google security advisories and CVE databases to apply patches promptly and adjust security policies accordingly.
