CVE-2026-19148
Description
A flaw was found in the GPU component of Google Chrome on Linux. A remote attacker, who has already compromised the renderer process, could exploit an out-of-bounds write vulnerability by tricking a user into visiting a specially crafted HTML page. This could potentially allow the attacker to escape the browser's sandbox, leading to further system compromise.
Statement
This Important vulnerability in the Chromium GPU component allows a compromised renderer process to perform a sandbox escape. While requiring prior compromise of the renderer and user interaction with a crafted HTML page, successful exploitation could lead to further system compromise beyond the browser's sandbox, elevating the risk due to the potential for broader system impact.
