CVE-2026-14418: Google Chrome ANGLE Information Disclosure

CVE-2026-14418 Overview

CVE-2026-14418 is an uninitialized memory use vulnerability in ANGLE, the graphics abstraction layer used by Google Chrome to translate OpenGL ES API calls to native graphics APIs. The flaw affects Google Chrome versions prior to 150.0.7871.46. A remote attacker can exploit the vulnerability by serving a crafted HTML page that triggers the uninitialized read within ANGLE, resulting in the leak of cross-origin data to the attacker. Chromium engineers rated the security severity as High, while the NVD assigns a medium CVSS score reflecting the limited confidentiality impact and requirement for user interaction. The weakness is classified under [CWE-457: Use of Uninitialized Variable].

Critical Impact
A remote attacker can leak cross-origin data from a victim's browser by luring the user to a crafted web page that abuses the ANGLE uninitialized memory condition.

Affected Products

Google Chrome desktop versions prior to 150.0.7871.46
Chromium-based browsers embedding vulnerable ANGLE builds
Applications and frameworks bundling affected Chromium/ANGLE components

Technical Details for CVE-2026-14418

Vulnerability Analysis

The vulnerability resides in ANGLE, the component that translates browser WebGL calls into platform-native graphics operations. ANGLE reads a memory region before it has been properly initialized, and the resulting stale contents flow back into JavaScript-observable state. Because the browser's same-origin policy relies on strict data segregation, uninitialized reads that surface graphics buffer residue can expose bytes belonging to other origins. Exploitation requires the victim to load an attacker-controlled HTML page containing crafted WebGL or graphics API calls. No authentication is required and the attack is executed remotely over the network.

Root Cause

The root cause is an uninitialized variable or buffer use in ANGLE ([CWE-457]). Code paths within the translation layer consume memory whose contents were not explicitly zeroed or written before being sampled. That stale memory can hold residual pixel, texture, or command buffer data from prior rendering operations, including data associated with different web origins.

Attack Vector

The attack vector is network-based via a crafted HTML page. The attacker hosts malicious content that invokes specific WebGL or graphics operations, reads back the resulting buffers, and reconstructs the leaked bytes. User interaction is required in the form of visiting or being redirected to the malicious page. No elevated privileges are needed on the target system.

No public proof-of-concept or verified exploit code is available for this issue. Technical details are tracked in the Chromium Issue Tracker Entry and the Google Chrome Update Release.

Detection Methods for CVE-2026-14418

Indicators of Compromise

Chrome browser processes reporting build versions earlier than 150.0.7871.46 on managed endpoints.
Outbound connections from browser processes to unknown domains immediately following WebGL-heavy page loads.
Unexpected GPU process crashes or ANGLE renderer errors coinciding with visits to untrusted sites.

Detection Strategies

Inventory installed Chrome and Chromium-based browser versions across the fleet and flag any build below 150.0.7871.46.
Correlate browser telemetry with proxy logs to identify sessions where WebGL content is loaded from low-reputation domains.
Monitor endpoint process trees for chrome.exe GPU child processes spawning anomalous network activity.

Monitoring Recommendations

Ingest browser version and patch-state telemetry into a central data lake to enable continuous exposure reporting.
Alert on new Chrome installations that lag the current stable channel by more than one release.
Track user navigation to newly registered or uncategorized domains that serve WebGL-enabled content.

How to Mitigate CVE-2026-14418

Immediate Actions Required

Update Google Chrome to version 150.0.7871.46 or later on all managed endpoints.
Force-restart browser sessions after deployment to ensure the patched binary is loaded.
Validate that Chromium-based third-party browsers and embedded webviews have pulled the corresponding ANGLE fix.

Patch Information

Google addressed the vulnerability in the Chrome stable channel update to 150.0.7871.46. Administrators should consult the Google Chrome Update Release for the full advisory and deploy the update through enterprise browser management tooling or standard software distribution channels.

Workarounds

Disable WebGL in Chrome via enterprise policy on high-risk endpoints until patching is complete.
Restrict browsing to trusted domains through web proxy allowlists for sensitive user groups.
Isolate high-value user sessions using remote browser isolation until the update propagates.
