This vulnerability (CVE-2026-10983) affects Google Chrome versions before 149.0.7827.53 and is caused by insufficient validation of untrusted input in the Dawn component. Exploitation could allow a remote attacker to escape the browser sandbox through a specially crafted HTML page, potentially leading to full compromise of the affected system. The CVSS 3.1 base score is 9.6 (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H), reflecting a network attack vector with low complexity, no privileges required, user interaction needed, and a scope change with high impact on confidentiality, integrity, and availability.

Successful exploitation could lead to a sandbox escape, allowing an attacker to execute code outside the browser's restricted environment. This could result in full system compromise, including unauthorized access to sensitive information, modification of data, and disruption of system availability. The vulnerability is rated critical due to its potential severity and ease of exploitation.
