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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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. A use-after-free occurs when a program continues to use a pointer to memory that has already been freed, potentially leading to arbitrary code execution. In this case, an attacker could craft a malicious HTML page to trigger this flaw and execute code within Chrome's sandbox.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your device through a specially crafted website. Since it affects Chrome's sandbox, the attacker would still face restrictions but could potentially bypass them to execute arbitrary code, compromising your system or stealing data.

Mitigation Strategies

Update Google Chrome to version 153.0.8010.47 or later to address the use after free vulnerability in V8.
