CVE-2026-14390 Overview
CVE-2026-14390 is a use-after-free vulnerability in ANGLE, the graphics abstraction layer used by Google Chrome to translate OpenGL ES calls to native GPU APIs. The flaw affects Google Chrome versions prior to 150.0.7871.46. A remote attacker can exploit the vulnerability through a crafted HTML page to potentially perform a sandbox escape. Chromium developers rated the security severity as High. The issue is tracked under CWE-416: Use After Free.
Critical Impact
Successful exploitation enables sandbox escape from the Chrome renderer process, allowing attackers to execute code outside the browser's security boundary via a malicious web page.
Affected Products
- Google Chrome versions prior to 150.0.7871.46
- Chromium-based browsers using the vulnerable ANGLE component
- Desktop platforms (Windows, macOS, Linux) running affected Chrome builds

Technical Details for CVE-2026-14390
Vulnerability Analysis
The vulnerability resides in ANGLE (Almost Native Graphics Layer Engine), which handles WebGL and GPU-accelerated rendering in Chrome. A use-after-free condition occurs when the component references memory that has already been freed. Attackers who trigger the flaw can corrupt heap state and manipulate freed object layouts.
Because ANGLE runs across the renderer and GPU process boundary, memory corruption here is particularly impactful. The advisory indicates the flaw permits a sandbox escape, meaning attacker-controlled code can break out of the Chrome renderer sandbox. This significantly amplifies impact compared to typical renderer-only bugs. Exploitation requires only that a user visits a crafted HTML page.
Root Cause
The defect is a use-after-free ([CWE-416]) inside ANGLE object lifecycle management. Specific technical details have not been disclosed publicly. The Chromium Issue Tracker Entry remains restricted pending broader patch adoption, following Google's standard disclosure practice.
Attack Vector
Exploitation is remote and requires user interaction. An attacker hosts a crafted HTML page that invokes WebGL or related GPU operations through ANGLE. When a victim visits the page, JavaScript triggers the vulnerable code path and manipulates freed memory. The scope is changed, indicating the exploit crosses trust boundaries into the GPU or browser process. The end result is potential sandbox escape and code execution outside the renderer.
No public proof-of-concept exploit or in-the-wild exploitation has been reported. See the Google Chrome Upgrade Blog for the vendor advisory.
Detection Methods for CVE-2026-14390
Indicators of Compromise
- Chrome renderer or GPU process crashes with heap corruption signatures shortly after visiting untrusted pages
- Unexpected child processes spawned by chrome.exe following browser sessions
- Outbound connections from Chrome helper processes to unfamiliar domains hosting WebGL-heavy content
Detection Strategies
- Inventory Chrome installations and flag hosts running versions below 150.0.7871.46
- Monitor endpoint telemetry for anomalous process creation, memory allocation patterns, or code injection originating from Chrome GPU processes
- Correlate browser crash dumps with visits to newly registered or low-reputation domains
Monitoring Recommendations
- Ingest browser crash reports and endpoint process telemetry into a centralized data lake for cross-host correlation
- Alert on Chrome versions that fall out of the supported patch level via software inventory feeds
- Track outbound web traffic to domains serving unusual WebGL payloads or shader-heavy content from unknown sources
How to Mitigate CVE-2026-14390
Immediate Actions Required
- Update Google Chrome to version 150.0.7871.46 or later on all managed endpoints
- Restart Chrome after updates to ensure the patched binaries are active
- Force-update through enterprise management policies where automatic updates are disabled
- Audit Chromium-based browsers (Edge, Brave, Opera, Vivaldi) and apply vendor updates that incorporate the ANGLE fix
Patch Information
Google released the fix in the Stable channel update documented on the Google Chrome Upgrade Blog. Users on version 150.0.7871.46 or later on desktop platforms are protected. Enterprise administrators should validate patch deployment through chrome://version or centralized software inventory tooling.
Workarounds
- Disable hardware acceleration in Chrome settings to reduce ANGLE code path exposure until patching completes
- Restrict WebGL through enterprise policy (WebGLEnabled = false) for high-risk user groups
- Enforce web filtering to block access to untrusted or newly registered domains
- Isolate browsing activity for privileged users in remote browser isolation environments
# Configuration example: enforce Chrome minimum version via enterprise policy (Windows)
reg add "HKLM\Software\Policies\Google\Chrome" /v "WebGLEnabled" /t REG_DWORD /d 0 /f
reg add "HKLM\Software\Policies\Google\Chrome" /v "HardwareAccelerationModeEnabled" /t REG_DWORD /d 0 /f
# Verify installed Chrome version
reg query "HKLM\Software\Google\Chrome\BLBeacon" /v version
