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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Google Chrome's Paint component. It occurs when a program continues to use memory after it has been freed, potentially allowing a remote attacker to execute arbitrary code within the browser's sandbox by tricking a user into visiting a specially crafted HTML page.

Impact Analysis

An attacker could exploit this to run malicious code on your device, potentially stealing data, installing malware, or taking control of your browser session. Since it requires user interaction (visiting a crafted page), the risk depends on avoiding untrusted websites.

Mitigation Strategies

Update Google Chrome to version 157.0.8103.38 or later to address the use-after-free vulnerability in Paint.
