CVE-2026-13883 Overview
CVE-2026-13883 is a type confusion vulnerability in ANGLE (Almost Native Graphics Layer Engine), the graphics abstraction layer used by Google Chrome to translate OpenGL ES calls to platform-native graphics APIs. The flaw affects Google Chrome versions prior to 150.0.7871.47. A remote attacker can exploit this vulnerability by convincing a user to visit a crafted HTML page, potentially leading to a sandbox escape. The issue is classified under CWE-843: Access of Resource Using Incompatible Type. Google Chrome's Stable channel update addresses the flaw across Windows, macOS, and Linux desktop builds.
Critical Impact
Successful exploitation allows an attacker to escape the Chrome renderer sandbox through a crafted web page, enabling code execution outside the browser's isolation boundary.
Affected Products
- Google Chrome prior to 150.0.7871.47
- Microsoft Windows desktop builds of Chrome
- Apple macOS and Linux desktop builds of Chrome

Technical Details for CVE-2026-13883
Vulnerability Analysis
CVE-2026-13883 is a type confusion flaw in ANGLE, the component Chrome uses to render WebGL content by translating OpenGL ES commands into Direct3D, Metal, or Vulkan calls. Type confusion occurs when code allocates or accesses a resource assuming one type, while the underlying object is of a different, incompatible type. In ANGLE's context, this mismatch can lead to reading or writing memory outside the expected object layout.
Because ANGLE processes untrusted GPU commands originating from web content, a crafted HTML page containing malicious WebGL shaders or draw calls can trigger the mismatch. Exploitation requires user interaction, specifically loading the attacker-controlled page. The scope of the vulnerability is marked as changed, indicating that a successful attack crosses the Chrome renderer sandbox boundary and affects components at a higher privilege level.
Root Cause
The root cause is improper type validation within ANGLE when handling graphics objects passed between the renderer process and the GPU process. When the code operates on an object under the wrong type assumption, memory adjacent to the object can be interpreted as fields it does not own, producing controllable memory corruption primitives usable to bypass sandbox constraints.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker hosts a malicious page that invokes specific WebGL or GPU-accelerated APIs. When the victim visits the page, the crafted content drives ANGLE into the type-confused state. The renderer process, normally sandboxed, can then leverage the confusion to influence the GPU process and escape the sandbox. See the Chromium Issue Tracker Entry for tracking details.
Detection Methods for CVE-2026-13883
Indicators of Compromise
- Chrome renderer or GPU process crashes with signatures pointing to libGLESv2 or ANGLE modules
- Unexpected child processes spawned by chrome.exe following visits to untrusted sites
- Outbound connections from Chrome GPU process to non-Google infrastructure shortly after page load
Detection Strategies
- Inventory installed Chrome versions across managed endpoints and flag any build below 150.0.7871.47
- Correlate browser crash telemetry with URL history to identify pages triggering ANGLE faults
- Hunt for post-exploitation behavior such as script interpreters or LOLBins launched as children of Chrome processes
Monitoring Recommendations
- Ingest Chrome browser and endpoint process telemetry into a centralized data lake for cross-host correlation
- Alert on Chrome processes writing executables or scheduled tasks, which indicate post-sandbox-escape activity
- Monitor WebGL-heavy or newly registered domains accessed by users, prioritizing rare-domain analytics
How to Mitigate CVE-2026-13883
Immediate Actions Required
- Update Google Chrome to version 150.0.7871.47 or later on all Windows, macOS, and Linux endpoints
- Force restart of the browser after update to ensure the patched ANGLE library is loaded
- Verify enterprise Chrome deployment policies are pulling from the Stable channel and not pinned to an older build
Patch Information
Google addressed the vulnerability in the Chrome Stable channel release documented in the Google Chrome Stable Update. Administrators managing Chrome via Group Policy, Jamf, or Intune should confirm that automatic updates are enabled and that the minimum version enforcement is set to 150.0.7871.47 or higher.
Workarounds
- Disable hardware acceleration in Chrome via chrome://settings to reduce ANGLE code path exposure until patching completes
- Restrict WebGL through enterprise policy by setting DefaultWebGLSetting to blocked for high-risk user groups
- Deploy browser isolation or restrict browsing to trusted domains for users unable to update immediately
# Configuration example: enforce minimum Chrome version via Group Policy registry key (Windows)
reg add "HKLM\SOFTWARE\Policies\Google\Chrome" /v TargetVersionPrefix /t REG_SZ /d "150.0.7871.47" /f
reg add "HKLM\SOFTWARE\Policies\Google\Chrome" /v DefaultWebGLSetting /t REG_DWORD /d 2 /f
