CVE-2025-12036Network attack vector

Out-of-bounds memory access via crafted HTML

Published Nov 6, 2025 · Updated Nov 6, 2025

Out-of-bounds memory access in V8 in Google Chrome before 142 allows remote attackers to trigger it via a crafted HTML page. Google labels the defect an inappropriate implementation in V8, but the restricted issue record does not disclose the affected function or faulty memory operation. A user must load the attacker-controlled page; successful exploitation exposes data, alters execution, or crashes the renderer.
