CVE-2025-14765 is a use-after-free vulnerability identified in the WebGPU implementation of Google Chrome versions prior to 143.0.7499.147. WebGPU is a web standard designed to provide modern graphics and computation capabilities within browsers. The vulnerability arises when a crafted HTML page triggers improper memory management, specifically a use-after-free condition, leading to heap corruption. This memory corruption can be exploited by remote attackers to execute arbitrary code within the context of the browser process. The flaw requires no privileges or prior authentication but does require user interaction, such as visiting a malicious webpage. The CVSS v3.1 score of 8.8 reflects high impact on confidentiality, integrity, and availability, with an attack vector over the network and low attack complexity. Although no exploits have been reported in the wild yet, the vulnerability's nature and severity make it a critical concern for users and organizations relying on Chrome for web access. The vulnerability was publicly disclosed on December 16, 2025, and affects all Chrome versions before 143.0.7499.147. No official patch links were provided in the data, but updating to the fixed version is essential. The vulnerability highlights the risks associated with complex browser features like WebGPU and the importance of rigorous memory safety in browser components.

The exploitation of CVE-2025-14765 can lead to full compromise of the affected system's browser process, allowing attackers to execute arbitrary code remotely. This can result in theft of sensitive data, installation of malware, or further lateral movement within an organization's network. The vulnerability impacts confidentiality by potentially exposing user data, integrity by allowing unauthorized code execution, and availability by causing crashes or denial of service. Since Chrome is widely used globally across personal, enterprise, and government environments, the scope of impact is extensive. Attackers could leverage this vulnerability to target high-value individuals or organizations by delivering malicious web content. The requirement for user interaction (visiting a malicious page) means phishing or drive-by download attacks are likely vectors. The absence of known exploits in the wild currently reduces immediate risk but does not diminish the urgency of remediation given the vulnerability's high severity and ease of exploitation.

Organizations and users should immediately update Google Chrome to version 143.0.7499.147 or later, where this vulnerability is fixed. In environments where immediate patching is not feasible, consider disabling or restricting WebGPU functionality via browser policies or enterprise configuration to reduce attack surface. Employ web filtering solutions to block access to known malicious websites and implement endpoint detection and response (EDR) tools to monitor for unusual browser behavior indicative of exploitation attempts. Educate users about the risks of interacting with untrusted web content and phishing campaigns. Regularly audit and update browser extensions and plugins to minimize additional vulnerabilities. Network-level protections such as intrusion prevention systems (IPS) can be tuned to detect exploit attempts targeting browser vulnerabilities. Finally, maintain comprehensive backup and incident response plans to mitigate potential damage from successful exploitation.
