Out of bounds read and write in WebGL in Google Chrome prior to 146.0.7680.153 allowed a remote attacker to perform arbitrary read/write via a crafted HTML page. (Chromium security severity: Critical)
AnalysisAI
This is a critical out-of-bounds read and write vulnerability in the WebGL implementation of Google Chrome prior to version 146.0.7680.153. The vulnerability allows a remote attacker to perform arbitrary memory read and write operations by crafting a malicious HTML page, potentially leading to information disclosure, code execution, or complete system compromise. The vulnerability affects multiple Debian releases and has been assigned ENISA EUVD ID EUVD-2026-13447; a vendor patch is available.
Technical ContextAI
WebGL is a JavaScript API for rendering interactive 2D and 3D graphics within web browsers without plugins. The vulnerability resides in Google Chrome's WebGL graphics processing pipeline and is classified as a buffer overflow (CWE-related memory safety issue). The root cause involves improper bounds checking in WebGL's memory management, allowing attackers to read from or write to memory regions outside the intended buffer allocation. This occurs at the rendering engine level where WebGL commands are processed and translated to GPU operations. The affected product is Google Chrome (CPE: cpe:2.3:a:google:chrome), with versions up to and including 146.0.7680.152 being vulnerable.
RemediationAI
Immediately upgrade Google Chrome to version 146.0.7680.153 or later. Users should enable automatic updates in Chrome settings (Settings > About Google Chrome) to ensure the patch is deployed automatically. For enterprise environments, administrators should use Chrome Enterprise policies to enforce minimum version requirements and disable WebGL if it is not required for business operations (via chrome://policies or Group Policy on Windows). Until patching is complete, users can reduce attack surface by disabling JavaScript execution in untrusted contexts, using content security policies (CSP) to restrict WebGL usage, and avoiding suspicious websites. The official Chrome release notes at chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_18.html provide patch availability confirmation.
