This security update for Chromium addresses numerous vulnerabilities across several versions. Notable fixes include CVE-2026-0628 (insufficient policy enforcement in WebView tag), CVE-2025-14765 (use after free in WebGPU), CVE-2025-14766 (out of bounds read and write in V8), CVE-2025-14174 (out of bounds memory access in ANGLE), CVE-2025-14372 (use after free in Password Manager), and multiple inappropriate implementation and use-after-free issues in components such as V8, Google Updater, DevTools, Digital Credentials, Downloads, Media Stream, WebRTC, and Passwords. Some vulnerabilities have known exploits in the wild, indicating active risk. The fixes are included in Chromium versions up to 143.0.7499.192.

The vulnerabilities could allow attackers to execute arbitrary code, cause memory corruption, or bypass security policies within Chromium. Components affected include critical browser subsystems such as the JavaScript engine (V8), WebGPU, WebView, and password management, potentially leading to unauthorized access or control over the browser environment. The presence of known exploits in the wild for at least one issue increases the urgency of applying updates.

Apply the security update to Chromium versions 143.0.7499.192 or later to remediate these vulnerabilities. Since this is a software update, upgrading to the fixed versions is the recommended and effective mitigation. No vendor advisory indicating 'no action required' or 'already mitigated' is provided, so timely patching is advised.
