CVE-2026-9900
Google · Chrome
An out-of-bounds write vulnerability in the ANGLE graphics engine of Google Chrome may allow a remote attacker to achieve sandbox escape via a crafted HTML page.
Executive summary
A critical out-of-bounds write vulnerability in the ANGLE component of Google Chrome could allow a remote attacker who has compromised the renderer process to escape the sandbox and execute arbitrary code.
Vulnerability
This flaw is an out-of-bounds write within the ANGLE graphics library. It allows an attacker who has successfully compromised the browser's renderer process to manipulate memory and potentially escape the sandbox environment using a specially crafted HTML page.
Business impact
With a CVSS score of 8.3, this vulnerability represents a significant risk to organizational security. Successful exploitation could grant an attacker the ability to execute code outside the browser's security boundaries, leading to full system compromise, data exfiltration, or the installation of persistent malicious software.
Remediation
Immediate Action: Apply the vendor-provided security update to version 148.0.7778.216 or higher across all enterprise endpoints.
Proactive Monitoring: Review web filtering and proxy logs for attempts to load malicious or obfuscated HTML content that may target browser graphics components.
Compensating Controls: Deploy robust EDR solutions capable of detecting memory-based attacks and process injection attempts originating from browser-related tasks.
Exploitation status
Public Exploit Available: False
Analyst recommendation
The risk of sandbox escape makes this vulnerability a high priority for remediation. Security teams must ensure that all users are running the patched version of Google Chrome to prevent potential exploitation via malicious web content.
