Technical Summary
CVE-2026-76020 is a race condition vulnerability in the V8 engine of Google Chrome before version 151.0.7922.173. Exploitation requires a remote attacker to deliver a specially crafted HTML page, which can trigger arbitrary code execution inside the sandbox. The vulnerability is classified under CWE-367 (Time-of-check Time-of-use Race Condition) and has a CVSS 3.1 base score of 7.5, indicating high severity.
