CVE-2025-11205 is a heap buffer overflow vulnerability identified in the WebGPU implementation of Google Chrome before version 141.0.7390.54. WebGPU is a web standard for graphics and computation on the GPU, enabling high-performance rendering and compute tasks within the browser. The vulnerability arises from improper handling of memory buffers in the WebGPU code, which can be triggered by a specially crafted HTML page. An attacker who has already compromised the renderer process—typically through another exploit or malicious content—can leverage this flaw to corrupt heap memory. This corruption can lead to arbitrary code execution, allowing the attacker to escalate privileges within the browser sandbox or execute code on the host system. The vulnerability does not require prior authentication or privileges but does require user interaction, such as visiting a malicious webpage. The CVSS v3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability, combined with low attack complexity and no privileges required. While no public exploits are currently known, the severity and potential impact make this a critical issue for Chrome users. The vulnerability was publicly disclosed on November 6, 2025, and Google has released a patched version (141.0.7390.54) to address it.

The impact of CVE-2025-11205 is significant for organizations globally due to the ubiquity of Google Chrome as a primary web browser. Successful exploitation can lead to full compromise of the affected system, including unauthorized data access, code execution, and potential lateral movement within corporate networks. This can result in data breaches, intellectual property theft, disruption of services, and installation of persistent malware or ransomware. Enterprises relying on Chrome for daily operations, especially those with sensitive or regulated data, face heightened risk. Additionally, the vulnerability could be leveraged in targeted attacks against high-value individuals or organizations by delivering malicious web content. The requirement for user interaction limits automated exploitation but does not eliminate risk, as phishing and drive-by download attacks remain common vectors. The absence of known exploits in the wild currently reduces immediate risk but does not preclude future exploitation once exploit code becomes available.

To mitigate CVE-2025-11205, organizations and users should immediately update Google Chrome to version 141.0.7390.54 or later, where the vulnerability is patched. Beyond patching, organizations should implement strict web content filtering and employ browser security features such as sandboxing and site isolation to limit the impact of compromised renderer processes. Deploy endpoint detection and response (EDR) solutions capable of identifying anomalous browser behavior indicative of exploitation attempts. Educate users to avoid clicking on suspicious links or visiting untrusted websites to reduce the risk of triggering the vulnerability. Network-level protections such as web proxies and intrusion prevention systems (IPS) can help block access to known malicious domains. For high-security environments, consider restricting or monitoring WebGPU usage or disabling it if not required. Regular vulnerability scanning and penetration testing should include checks for outdated browser versions and exploitation attempts related to this vulnerability.
