An out-of-bounds write vulnerability exists in the Skia graphics library component of Google Chrome versions before 151.0.7922.109. This vulnerability allows a remote attacker, who has already compromised the renderer process, to potentially perform a sandbox escape by delivering a specially crafted HTML page. The issue is tracked as CVE-2026-19173 and is rated high severity by Chromium security. The vulnerability is addressed in Chrome version 151.0.7922.109 as indicated by the versioning and the vendor's stable channel update blog post.

Successful exploitation of this vulnerability could allow an attacker with control over the renderer process to escape the sandbox environment, potentially gaining higher privileges on the host system. This increases the risk of further compromise beyond the browser sandbox, including arbitrary code execution with elevated privileges.

Users and administrators should update Google Chrome to version 151.0.7922.109 or later to remediate this vulnerability. The vendor advisory linked confirms this update as the fix. No additional mitigation steps are specified or required beyond applying the official update.
