Summary
A flaw was found in chromium-browser. A remote attacker could exploit a type confusion vulnerability in the V8 JavaScript engine by enticing a user to visit a specially crafted HTML page.
This could allow the attacker to execute arbitrary code within the browser's sandbox, potentially compromising the user's system. Exploitation requires user interaction, specifically visiting a specially crafted HTML page, but the potential for remote code execution elevates its severity.
Red Hat severity: Important — CVSS 8.3 (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H). Weakness: CWE-843.
