CVE-2025-3068 is a vulnerability identified in Google Chrome for Android prior to version 135.0.7049.52, stemming from an inappropriate implementation of Intents, a core Android mechanism used for inter-application communication. This flaw allows a remote attacker to craft a malicious HTML page that, when visited by a user, can trigger privilege escalation within the Chrome browser context. The vulnerability is rooted in improper input validation (CWE-20), where the Intents handling logic fails to adequately verify or sanitize incoming data, enabling unauthorized elevation of privileges. The attack vector requires no prior privileges (PR:N) but does require user interaction (UI:R), such as visiting a malicious webpage. The vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H), as an attacker could potentially execute arbitrary code or gain elevated permissions within the browser sandbox, compromising user data and system stability. The CVSS v3.1 base score of 8.8 reflects the high severity and ease of exploitation over a network (AV:N) with low attack complexity (AC:L). Although no known exploits have been reported in the wild, the widespread use of Chrome on Android devices makes this a significant threat. The vulnerability was publicly disclosed on April 2, 2025, and no patch links were provided in the source data, indicating the urgency for users to update as soon as a fix is available.

The impact of CVE-2025-3068 is substantial for organizations and individual users relying on Google Chrome on Android devices. Successful exploitation can lead to privilege escalation, allowing attackers to bypass security restrictions and potentially execute arbitrary code within the browser environment. This can result in unauthorized access to sensitive information, manipulation or corruption of data, and disruption of service availability. For enterprises, this could mean exposure of confidential corporate data, compromise of mobile device management controls, and increased risk of lateral movement within networks if mobile devices are used as entry points. The vulnerability's exploitation requires only user interaction, increasing the likelihood of successful attacks through phishing or malicious websites. Given the global dominance of Chrome on Android, the scope of affected systems is vast, impacting sectors including finance, healthcare, government, and critical infrastructure. The absence of known exploits in the wild provides a window for proactive mitigation, but the high CVSS score underscores the urgency to address this vulnerability promptly.

To mitigate CVE-2025-3068 effectively, organizations and users should: 1) Immediately update Google Chrome on Android devices to version 135.0.7049.52 or later once the patch is available to ensure the vulnerability is remediated. 2) Implement strict mobile device management (MDM) policies that enforce timely application updates and restrict installation of untrusted applications or browsing of unverified websites. 3) Educate users about the risks of interacting with unknown or suspicious web content, emphasizing caution with links received via email, messaging apps, or social media. 4) Employ network-level protections such as web filtering and intrusion detection systems to block access to known malicious domains and monitor for anomalous browser behavior. 5) Utilize application sandboxing and least privilege principles on mobile devices to limit the potential impact of any successful exploit. 6) Monitor security advisories from Google and related threat intelligence sources for updates on exploit availability and additional mitigations. 7) Consider deploying endpoint detection and response (EDR) solutions capable of identifying exploitation attempts targeting browser vulnerabilities on mobile platforms. These targeted measures go beyond generic advice by focusing on proactive patch management, user awareness, and layered defenses tailored to mobile browser exploitation.
