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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 the UI component of Google Chrome versions before 152.0.7977.65. A use-after-free occurs when a program continues to use a pointer after the memory it points to has been freed, potentially leading to crashes or arbitrary code execution.

Impact Analysis

If exploited, this vulnerability could allow a local attacker who has already compromised the renderer process to execute arbitrary code outside the browser's sandbox. This could lead to unauthorized access to system resources or data, potentially compromising the entire system.

Mitigation Strategies

Update Google Chrome to version 152.0.7977.65 or later to address the use after free vulnerability in the UI component.
