Heap buffer overflow in WebGL in Google Chrome prior to 146.0.7680.165 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Google Chrome's WebGL implementation contains a heap buffer overflow that enables remote attackers to read arbitrary memory by serving a specially crafted HTML page to users prior to version 146.0.7680.165. This network-based vulnerability requires only user interaction and affects Chrome on all platforms, granting attackers access to sensitive data in the browser's memory. A patch is available and should be applied immediately given the high severity and potential for exploitation.
Technical ContextAI
This vulnerability resides in WebGL (Web Graphics Library), a JavaScript API for rendering 2D and 3D graphics within web browsers. WebGL is implemented natively in Chromium-based browsers and interfaces with the underlying graphics drivers via OpenGL or Direct3D. The root cause, classified as CWE-122 (Heap-based Buffer Overflow), indicates that the WebGL implementation fails to properly validate buffer boundaries when processing graphics commands or shader data. An attacker crafts malicious WebGL calls that cause the renderer process to write or read beyond allocated heap memory regions. The CPE designation (cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*) confirms the vulnerability affects all versions of Google Chrome prior to the patched release 146.0.7680.165.
RemediationAI
Upgrade Google Chrome to version 146.0.7680.165 or later immediately. Chrome will typically update automatically in the background, but users should verify their version via chrome://settings/help and restart the browser if an update is available. For enterprise environments, deploy the patched version through your managed deployment tools (Google Admin Console, Windows Group Policy, or macOS configuration profiles) as soon as possible. Until devices can be patched, restrict user access to untrusted websites and consider using security policies to limit WebGL functionality if absolutely necessary, though this may degrade web application functionality. Monitor the Chrome Releases blog (https://chromereleases.googleblog.com/) and the Chromium security issue tracker (https://issues.chromium.org/) for any updates regarding active exploitation or bypass techniques.
