CVE-2026-17726 describes a high-severity integer overflow vulnerability in the WebGL component of Google Chrome on Android. The flaw exists in versions prior to 151.0.7922.72 and can be exploited by a remote attacker via a specially crafted HTML page. Successful exploitation could potentially allow a sandbox escape, granting the attacker elevated access beyond the browser's security boundary. The vulnerability was assigned a 'High' severity rating by the Chromium security team. Google has addressed the issue in the stable channel update released in July 2026. Users are strongly advised to update their Chrome for Android installations to version 151.0.7922.72 or later. The issue was tracked internally in the Chromium issue tracker under issue #529867799. No active exploitation in the wild has been mentioned, but the sandbox escape potential makes this a critical concern for Android users.
