CVE-2024-0223Network attack vector

Heap corruption via ANGLE buffer overflow

Published Jan 4, 2024 · Updated Jun 18, 2025

Heap buffer overflow in ANGLE in Google Chrome before 120.0.6099.199 allows remote attackers to corrupt heap memory via crafted HTML. Google's public bulletin identifies ANGLE but leaves the affected routine and the incorrect bounds or allocation operation undisclosed because the linked issue remains restricted. A browser user must load the crafted page; public sources do not establish a resulting browser crash, code execution, or sandbox escape.
