CVE-2025-10500Network attack vector

Heap corruption via Dawn use-after-free

Published Sep 24, 2025 · Updated Sep 24, 2025

Use-after-free in Dawn in Google Chrome before 140.0.7339.185 allows remote attackers to corrupt heap memory via crafted HTML. Google identifies the affected Dawn component but keeps the underlying bug details restricted, so the freed object's lifetime error and triggering operation are undisclosed. A user must load attacker-controlled HTML; the published record does not specify whether exploitation stops at a crash or reaches code execution inside the browser sandbox.
