Type Confusion in ANGLE in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Critical)

AnalysisAI

Heap corruption in Google Chrome's ANGLE graphics translation layer prior to version 149.0.7827.53 allows remote attackers to potentially achieve code execution by enticing a user to visit a crafted HTML page. Chromium rates the severity as Critical and the CVSS score is 8.8 (High), but no public exploit identified at time of analysis. The flaw is a type confusion issue that maps to CWE-787 (out-of-bounds write), affecting the browser's WebGL/graphics rendering path.

Technical ContextAI

ANGLE (Almost Native Graphics Layer Engine) is the abstraction library Chrome uses to translate OpenGL ES API calls into native graphics APIs such as Direct3D, Metal, or Vulkan, enabling WebGL and other GPU-accelerated web content across platforms. A type confusion bug in ANGLE means the engine interprets a memory object as a different type than it actually is, which in C++ graphics code typically corrupts heap metadata or object vtables. The CWE-787 classification (out-of-bounds write) indicates the type confusion leads to writing beyond allocated buffer boundaries, the same primitive that has historically yielded reliable browser RCE via heap grooming and pointer overwrites. Because ANGLE is reachable from any web page that uses WebGL or 2D canvas acceleration, the attack surface is exposed to all untrusted web content the browser renders.

RemediationAI

Vendor-released patch: Google Chrome 149.0.7827.53 - update Chrome via the built-in updater or by downloading from Google and restarting the browser to complete the update, as documented in the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html. For managed fleets, push the update via Group Policy, Intune, Jamf, or your endpoint management tool and verify chrome://version reports 149.0.7827.53 or later; downstream Chromium browsers (Edge, Brave, Opera, Electron apps) should be updated as their vendors ship the corresponding ANGLE fix. As an interim compensating control where immediate patching is not possible, WebGL can be disabled via the enterprise policy 'HardwareAccelerationModeEnabled=false' or by toggling chrome://flags, which reduces the ANGLE attack surface at the cost of breaking WebGL-dependent sites and degrading graphics performance; restricting browsing to trusted sites via SafeSites/URL allowlists offers partial mitigation but does not protect against compromised or malvertising-laden trusted domains.
