Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This is a use-after-free vulnerability in Blink, the rendering engine of Google Chrome. It allows a remote attacker to execute arbitrary code within a sandbox by tricking a user into visiting a specially crafted HTML page. The issue arises when Chrome improperly handles memory after it has been freed, leading to potential code execution.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your device, potentially stealing data, installing malware, or taking control of your browser. Since it requires user interaction (visiting a malicious page), keeping software updated reduces risk.

Mitigation Strategies

Update Google Chrome to version 150.0.7871.186 or later to address the use after free vulnerability in Blink.
