About this tag
CVE-2026-1220 is a high-severity vulnerability in the V8 JavaScript engine, described as a 'Race in V8' by Google. Google released an out-of-band Stable channel update for Chrome on January 20, 2026 to fix this bug.

The vulnerability underscores the importance of patching Chromium-based browsers promptly and monitoring vendor advisories for ingestion of upstream security fixes.
