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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 V8, the JavaScript engine used by Google Chrome. It occurs when a program tries to use memory that has already been freed, potentially leading to arbitrary code execution. The vulnerability exists in Chrome versions prior to 155.0.8059.84 and can be triggered by a specially crafted HTML page.

Impact Analysis

An attacker could exploit this to execute arbitrary code on your system. Since it's inside the sandbox, the impact is limited to the browser's sandboxed environment. However, this could still allow the attacker to steal data, install malware, or perform other malicious actions within the browser.

Mitigation Strategies

Update Google Chrome to version 155.0.8059.84 or later to address the use after free vulnerability in V8.
