DescriptionCVE.org

Out of bounds read in ANGLE in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Out-of-bounds memory read in the ANGLE graphics translation layer of Google Chrome before 149.0.7827.53 allows a remote attacker to leak adjacent memory contents when a victim visits a crafted HTML page. No public exploit identified at time of analysis, and EPSS rates exploitation probability at just 0.03%, but the CVSS 8.1 score reflects the user-interaction-only barrier combined with high confidentiality and availability impact. Google has shipped a stable-channel fix and Chromium rates the underlying severity as Medium.

Technical ContextAI

ANGLE (Almost Native Graphics Layer Engine) is the abstraction library Chrome uses to translate OpenGL ES API calls into the host platform's native graphics API (Direct3D on Windows, Metal on macOS, Vulkan/OpenGL on Linux), and it underpins WebGL rendering in the renderer process. The flaw is classified as CWE-125 (Out-of-Bounds Read), meaning a parser or shader/buffer handler in ANGLE reads past an allocated buffer boundary, exposing uninitialized or adjacent process memory. Because ANGLE runs inside the sandboxed renderer, primary impact is information disclosure (potentially including pointers useful for ASLR bypass) and renderer instability rather than direct sandbox escape.

RemediationAI

Vendor-released patch: Google Chrome 149.0.7827.53 - update Chrome desktop to 149.0.7827.53 or later via the built-in updater (chrome://settings/help) and relaunch the browser, as documented in the Stable Channel update at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html and tracked in Chromium issue https://issues.chromium.org/issues/500530720. Managed environments should push the update through enterprise tooling (Group Policy, Jamf, Intune, or Google Admin console) and verify version compliance. Until rollout completes, a compensating control is to disable hardware-accelerated WebGL by toggling chrome://flags/#disable-webgl or via the WebGLAllowed enterprise policy set to false, which neutralizes the ANGLE attack surface at the cost of breaking 3D content, map renderings, and some video acceleration; for downstream Chromium browsers (Edge, Brave, Opera, Vivaldi), apply the equivalent vendor update once they rebase onto a Chromium ≥149.0.7827.53.
