DescriptionCVE.org

Inappropriate implementation in WebGL in Google Chrome prior to 146.0.7680.178 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Information disclosure in Google Chrome's WebGL implementation prior to version 146.0.7680.178 allows remote attackers to extract potentially sensitive data from process memory by serving a crafted HTML page. The vulnerability affects all Chrome versions before the patched release and requires only user interaction (visiting a malicious webpage) to trigger memory disclosure via WebGL rendering.

Technical ContextAI

WebGL is a JavaScript API that enables 3D graphics rendering in web browsers by providing low-level access to GPU functionality. Inappropriate implementation in Chrome's WebGL stack allowed memory contents to leak through GPU or rendering pipeline state exposure. This likely involves failure to properly isolate or sanitize GPU memory buffers, shader outputs, or texture data that could contain sensitive process memory. The vulnerability is classified as CWE-scope boundary violation or memory exposure, affecting the rendering engine's memory safety guarantees when processing WebGL commands from untrusted web content. Google Chrome versions before 146.0.7680.178 (across all platforms covered by CPE a:google:chrome) are affected.

RemediationAI

Update Google Chrome to version 146.0.7680.178 or later, which contains the fix for the WebGL implementation flaw. Users can enable automatic updates to receive the patch immediately, or manually trigger a browser restart to install pending updates via the Settings menu. No workarounds are available for older versions; patching is the only mitigation. Refer to the official Chrome releases announcement at https://chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_31.html and the Chromium bug tracker at https://issues.chromium.org/issues/490118036 for additional technical details.
