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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 vulnerability is a use-after-free issue in Dawn, a component 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 exists in Chrome versions prior to 151.0.7922.72.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 151.0.7922.72. To detect it, check your Chrome version by running chrome --version or chrome://version in the browser. If your version is below 151.0.7922.72, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your device, potentially leading to unauthorized access, data theft, or installation of malware. However, the sandbox limits the impact, reducing the risk of severe damage.
