CVE-2026-2315 is a vulnerability identified in the WebGPU component of Google Chrome versions prior to 145.0.7632.45. WebGPU is a web standard designed to provide modern graphics and compute capabilities within browsers, enabling high-performance GPU access. The vulnerability arises from an inappropriate implementation that allows a remote attacker to cause out-of-bounds memory access by crafting a malicious HTML page that leverages WebGPU APIs. This out-of-bounds access can lead to memory corruption, which attackers might exploit to execute arbitrary code, escalate privileges, or cause denial of service. The attack vector is remote and requires the victim to load a malicious webpage, meaning user interaction is necessary but no prior authentication is required. The vulnerability was assigned a high severity by Chromium security but lacks an official CVSS score. No public exploits have been reported yet, but the potential for exploitation is significant given the widespread use of Chrome and the nature of the vulnerability. The patch was released in Chrome version 145.0.7632.45, which addresses the improper memory handling in WebGPU. Given the critical role of browsers in enterprise environments, this vulnerability represents a serious risk if left unpatched.

For European organizations, this vulnerability poses a substantial risk due to the widespread adoption of Google Chrome as the primary web browser. Exploitation could lead to unauthorized code execution within the context of the browser, potentially compromising sensitive data, user credentials, or enabling lateral movement within networks. Sectors such as finance, healthcare, government, and critical infrastructure, which rely heavily on secure web access, are particularly vulnerable. The out-of-bounds memory access could also be leveraged to bypass security controls or sandboxing mechanisms, increasing the risk of persistent compromise. Additionally, organizations with remote or hybrid workforces are at increased risk as users may access malicious sites from less secure environments. The lack of known exploits currently provides a window for proactive mitigation, but the high severity rating indicates that attackers may develop exploits rapidly. Failure to update could result in data breaches, service disruptions, and reputational damage.

1. Immediately update all Google Chrome installations to version 145.0.7632.45 or later to apply the official patch addressing this vulnerability. 2. Employ enterprise browser management tools to enforce automatic updates and prevent use of outdated versions. 3. Restrict or disable WebGPU functionality via browser policies or group policies where feasible, especially in high-risk environments. 4. Implement web content filtering and URL reputation services to block access to potentially malicious sites. 5. Educate users about the risks of visiting untrusted websites and encourage cautious browsing behavior. 6. Monitor network traffic and endpoint logs for unusual activity indicative of exploitation attempts. 7. Use sandboxing and endpoint protection solutions that can detect and prevent exploitation of memory corruption vulnerabilities. 8. Coordinate with IT and security teams to ensure rapid incident response capabilities in case of exploitation. 9. Review and update incident response and patch management policies to prioritize browser vulnerabilities. 10. Consider deploying browser isolation technologies for high-risk user groups to contain potential attacks.
