CVE-2026-14396: Google Chrome ANGLE Information Disclosure

CVE-2026-14396 Overview

CVE-2026-14396 is an out-of-bounds read vulnerability in ANGLE, the graphics abstraction layer that translates OpenGL ES calls to native graphics APIs in Google Chrome. The flaw affects Chrome versions prior to 150.0.7871.46. A remote attacker can leak cross-origin data by serving a crafted HTML page to a targeted user. Google classifies the Chromium security severity as High. The weakness is tracked as CWE-125 (Out-of-bounds Read).

Critical Impact
A remote attacker can exfiltrate cross-origin data from the victim's browser process by luring the user to a malicious web page containing crafted WebGL content.

Affected Products

Google Chrome desktop versions prior to 150.0.7871.46
Chromium-based browsers embedding vulnerable ANGLE builds
Applications relying on Chromium's WebGL/ANGLE rendering pipeline

Technical Details for CVE-2026-14396

Vulnerability Analysis

The vulnerability resides in ANGLE (Almost Native Graphics Layer Engine), the component Chrome uses to implement WebGL by translating OpenGL ES commands to Direct3D, Vulkan, or Metal. An out-of-bounds read occurs when ANGLE processes attacker-influenced graphics state or buffers and reads memory beyond an allocated region. The read discloses adjacent process memory back to the JavaScript context that issued the WebGL call. Because the GPU process handles rendering for multiple origins, leaked bytes can include cross-origin pixel data, texture contents, or other sensitive process state. The issue is tracked in the Chromium Issue Tracker.

Root Cause

The root cause is missing or incorrect bounds validation on an index, length, or size parameter used during a graphics operation inside ANGLE. When the parameter exceeds the intended buffer extent, the read proceeds into unrelated memory instead of returning an error. The CWE-125 classification confirms the flaw is a boundary condition error in read logic rather than a write primitive.

Attack Vector

Exploitation requires a victim to load a crafted HTML page in a vulnerable Chrome build. The page issues WebGL calls that reach the vulnerable ANGLE code path and reads back results through APIs such as readPixels or shader outputs. No authentication or user interaction beyond visiting the page is required. The attacker uses the leaked bytes to reconstruct cross-origin content, defeating the same-origin policy enforced by the browser. See the Chrome Stable Channel Update for the vendor's advisory.

No verified public exploit code is available at this time. Technical details are described in prose to avoid speculation.

Detection Methods for CVE-2026-14396

Indicators of Compromise

Chrome processes running versions earlier than 150.0.7871.46 on managed endpoints
Browser navigations to untrusted domains that immediately initialize WebGL contexts and issue large readPixels operations
GPU process crashes or anomalous memory access reports in Chrome crash telemetry correlated with WebGL activity

Detection Strategies

Inventory installed Chrome versions across the fleet and flag any build prior to 150.0.7871.46
Correlate web proxy logs with endpoint telemetry to identify users visiting pages that heavily exercise WebGL from low-reputation origins
Monitor Chromium crash reports for GPU process faults referencing ANGLE modules

Monitoring Recommendations

Ingest browser version and patch state from endpoint agents into a central data lake for continuous compliance reporting
Alert on outbound connections to newly registered domains that serve WebGL-heavy content to executives or high-value users
Track EPSS movement for CVE-2026-14396 (currently 0.174%) to detect changes in real-world exploitation likelihood

How to Mitigate CVE-2026-14396

Immediate Actions Required

Update Google Chrome to version 150.0.7871.46 or later on all managed endpoints
Force-restart Chrome after deployment so the patched binary is loaded into memory
Verify Chromium-based browsers and embedded webviews in your environment have consumed the corresponding ANGLE fix

Patch Information

Google released the fix in the Chrome stable channel as documented in the Chrome Stable Channel Update. The patched build is 150.0.7871.46 for desktop platforms. Enterprises using Chrome Browser Cloud Management or group policy should push the update through their existing channels and confirm rollout with version telemetry.

Workarounds

Disable WebGL via the enterprise policy WebGLEnabled=false where business use cases permit
Restrict browsing to trusted origins using URL allowlists until patching is complete
Isolate high-risk browsing in a hardened virtual machine or remote browser isolation service

bash

# Verify Chrome version on Linux/macOS endpoints
google-chrome --version

# Windows group policy registry key to disable WebGL as a temporary workaround
reg add "HKLM\Software\Policies\Google\Chrome" /v WebGLEnabled /t REG_DWORD /d 0 /f
