Google Chrome: Improper access control in ANGLE graphics layer
Summary
Improper access control in ANGLE, the graphics layer of Google Chrome, affects Chrome versions before 156.0.8078.47. A remote attacker who gets a user to open a crafted HTML page could potentially execute arbitrary code inside the browser sandbox. The sandbox is not reported as escaped, and Chromium rates the issue Low. No active exploitation or public proof of concept is known.
