CVE-2025-12725 is a critical memory safety vulnerability identified in the WebGPU implementation of Google Chrome on Android platforms prior to version 142.0.7444.137. The flaw is characterized as an out of bounds read that can be leveraged by a remote attacker to perform an out of bounds write operation in memory. This vulnerability arises from improper bounds checking within the WebGPU component, which is responsible for providing high-performance graphics and computation capabilities in the browser. An attacker can craft a malicious HTML page that, when loaded by a vulnerable Chrome browser on Android, triggers this memory corruption. The out of bounds write can lead to arbitrary code execution, allowing the attacker to compromise the browser process and potentially escalate privileges on the device. The vulnerability does not require any prior authentication but does require user interaction, such as visiting a malicious or compromised website. The CVSS v3.1 base score of 8.8 reflects the high impact on confidentiality, integrity, and availability, combined with the ease of exploitation over the network with low attack complexity. Although no active exploits have been reported in the wild, the potential for exploitation is significant given the widespread use of Chrome on Android devices and the critical nature of the flaw. The vulnerability was publicly disclosed on November 10, 2025, and users are urged to update to the patched version 142.0.7444.137 or later to remediate the issue.

The impact of CVE-2025-12725 is substantial for organizations and individual users relying on Google Chrome on Android devices. Exploitation can lead to arbitrary code execution within the browser context, enabling attackers to steal sensitive information, manipulate data, or disrupt device functionality. This can result in loss of confidentiality through data leakage, integrity violations by altering data or browser behavior, and availability issues via crashes or denial of service. For enterprises, compromised mobile devices can serve as entry points into corporate networks, leading to broader security breaches. The vulnerability's remote exploitability and lack of required privileges increase the risk of widespread attacks, especially in environments where users frequently browse untrusted websites. The absence of known exploits currently provides a window for proactive patching, but the high severity score indicates that attackers may develop exploits rapidly. Organizations with mobile workforces, especially those handling sensitive or regulated data, face elevated risks from this vulnerability.

To mitigate CVE-2025-12725, organizations and users should immediately update Google Chrome on Android devices to version 142.0.7444.137 or later, where the vulnerability has been patched. Beyond patching, organizations should implement web content filtering and DNS filtering to block access to known malicious or suspicious websites that could host exploit pages. Employing mobile device management (MDM) solutions to enforce browser updates and restrict installation of untrusted applications can reduce exposure. Network-level protections such as intrusion detection systems (IDS) and web proxies with advanced threat detection can help identify and block exploit attempts. Educating users about the risks of visiting untrusted websites and the importance of prompt browser updates is critical. Additionally, monitoring for unusual browser behavior or crashes on Android devices can provide early indicators of exploitation attempts. Given the vulnerability requires user interaction, minimizing exposure to phishing or drive-by download attacks through email and web security controls is also recommended.
