A Use-After-Free vulnerability in the Blink rendering engine of Google Chrome could allow an unauthenticated attacker to execute arbitrary code.

Executive summary

The Blink rendering engine in Google Chrome is susceptible to a high-severity Use-After-Free vulnerability that could lead to arbitrary code execution.

Vulnerability

This is a Use-After-Free (UAF) vulnerability within Blink, the core rendering engine for Chrome. An unauthenticated attacker can exploit this by tricking a user into navigating to a malicious site, resulting in memory corruption and potential code execution.

Business impact
