CVE-2026-14398 Overview
CVE-2026-14398 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 and allows a remote attacker to potentially perform a sandbox escape through a crafted HTML page. Chromium classifies the security severity as Critical. The weakness is tracked under CWE-416.
Critical Impact
A remote attacker can trigger memory corruption in the GPU process and escape the Chrome renderer sandbox by luring a user to a malicious web page.
Affected Products
- Google Chrome versions prior to 150.0.7871.46
- Chromium-based browsers embedding vulnerable ANGLE builds
- Desktop platforms served by the Chrome Stable channel

Technical Details for CVE-2026-14398
Vulnerability Analysis
The vulnerability resides in ANGLE (Almost Native Graphics Layer Engine), which brokers WebGL and GPU operations for Chrome. A use-after-free condition arises when ANGLE continues to reference a memory object after it has been released. An attacker who controls the freed allocation can influence subsequent reads or writes to that memory region.
Chrome's ANGLE runs inside the GPU process, which historically presents a valuable target for sandbox escapes. Successful exploitation can pivot from renderer-level code execution to the more privileged GPU process. This bridges the boundary that normally isolates web content from the host system.
The attack requires user interaction, typically loading a crafted HTML page containing malicious WebGL or Canvas content. The scope is marked as changed, indicating that impact extends beyond the initially vulnerable component. Confidentiality, integrity, and availability are each rated high.
Root Cause
The root cause is improper lifetime management of a graphics resource inside ANGLE. Code paths retain a dangling pointer to an object after it has been freed, and later dereference that pointer. Attackers reclaim the freed slot with attacker-controlled data to corrupt program state.
Attack Vector
Exploitation is network-based and requires a victim to visit or be redirected to a malicious page. The crafted HTML triggers the vulnerable ANGLE code path through WebGL, Canvas, or related GPU-accelerated rendering APIs. No authentication is required, and attack complexity is low.
Details of the exploit primitive are described in the Chromium Issue Tracker Entry and the Google Chrome Stable Update.
Detection Methods for CVE-2026-14398
Indicators of Compromise
- Chrome GPU process crashes with signatures referencing ANGLE, libGLESv2, or WebGL contexts
- Unexpected child process creation from chrome.exe following visits to untrusted pages
- Outbound connections from Chrome sub-processes to unfamiliar infrastructure shortly after browsing activity
Detection Strategies
- Monitor endpoints for Chrome versions below 150.0.7871.46 using software inventory tooling
- Alert on repeated GPU process termination events correlated with specific navigation URLs in browser telemetry
- Correlate WebGL-heavy page loads with subsequent anomalous process behavior originating from Chrome
Monitoring Recommendations
- Ingest browser and endpoint telemetry into a centralized analytics platform to identify post-exploitation activity
- Track Chrome update status across the fleet and flag hosts that fail to apply Stable channel updates
- Review DNS and proxy logs for access to newly registered domains preceding Chrome crashes
How to Mitigate CVE-2026-14398
Immediate Actions Required
- Update Google Chrome to version 150.0.7871.46 or later on all managed endpoints
- Restart browsers after patching to ensure the vulnerable ANGLE binary is unloaded from memory
- Audit Chromium-based applications and Electron builds for embedded ANGLE versions that require rebasing
Patch Information
Google released a fix in the Chrome Stable channel version 150.0.7871.46. Refer to the Google Chrome Stable Update announcement for full release notes. Enterprise administrators can enforce the update through Chrome Browser Cloud Management or standard software distribution tooling.
Workarounds
- Disable hardware acceleration in Chrome via chrome://settings to reduce reliance on ANGLE code paths until patching completes
- Restrict WebGL through enterprise policy on unpatched systems by configuring DefaultWebGLSetting
- Block access to untrusted web content using web filtering or browser isolation for high-risk user groups
# Enterprise policy example to disable WebGL until patching is complete
# Windows registry (HKLM\Software\Policies\Google\Chrome)
DefaultWebGLSetting = 2 # 2 = Block WebGL
HardwareAccelerationModeEnabled = 0
