CVE-2026-3909: Google Skia out-of-bounds write in Google Chrome

CVE-2026-3909 · Severity: critical · CVSS 8.8 · Exploited in the wild · Published 2026-03-13

Technologies: Google Chrome, Google Android, Google ChromeOS, Google Skia. Vendors: Google.

Executive brief

Google Skia, a graphics engine used in web browsers and mobile operating systems, contains a critical security flaw that allows attackers to corrupt system memory. By tricking a user into visiting a specially crafted website, an attacker could potentially execute malicious code or crash the application. This vulnerability is particularly serious as it has been observed being used in active attacks in the wild.

Technical details

An out-of-bounds (OOB) write vulnerability (CWE-787) exists in the Skia graphics library as integrated into Google Chrome and other products. The flaw is triggered when the engine processes a specially crafted HTML page, leading to unauthorized memory access. This is a remote attack vector that requires minimal user interaction (visiting a URL) and no prior authentication. Successful exploitation can lead to arbitrary code execution within the context of the browser renderer process or a denial-of-service condition. Google has released patches in Chrome version 146.0.7680.75 and later to address this issue.
