Security update for chromium

The update for Chromium versions 152.0.7977.75 and 152.0.7977.82 fixes numerous security issues including CVE-2026-84323 and others. Vulnerabilities include use-after-free errors in multiple components (Shared Tab Groups, WebGL, Proxy, Browser, Dawn, WebRTC, TabStrip), type confusion in V8 and Compositing, out-of-bounds read and write errors, improper input validation, incorrect authorization checks in FileSystem, Navigation, SiteSettings, Chromoting, TabStrip, Autofill, and Actor components, information leaks in Skia and MediaCapture, race conditions in V8, buffer overflow in GPU, and UI misrepresentation in FullScreen. These issues collectively represent critical security risks. The update disables the EULA dialog to improve configuration handling. The vendor has released patches for these vulnerabilities in the specified Chromium versions.

The vulnerabilities fixed in this update are critical and could allow attackers to execute arbitrary code, cause denial of service, escalate privileges, or leak sensitive information. The range of affected components and types of vulnerabilities increases the attack surface significantly. Without applying these patches, systems running the affected Chromium versions are at high risk of compromise.

A security update is available that addresses all listed vulnerabilities in Chromium versions 152.0.7977.75 and 152.0.7977.82. Users and administrators should apply these updates promptly to mitigate the critical security risks. No additional vendor advisories indicate that no action is required or that these are already mitigated, so patching is the recommended course of action.
