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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 the PerformanceAPIs component of Google Chrome versions prior to 156.0.8078.47. 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 arbitrary code execution. In this case, a remote attacker could exploit this by crafting a malicious HTML page to trigger the flaw.

Impact Analysis

This vulnerability could allow a remote attacker to execute arbitrary code on your system outside the browser's sandbox. This means they might gain control over your computer, install malware, or steal sensitive data. Users of affected Chrome versions are at risk if they visit a malicious website.

Mitigation Strategies

Update Google Chrome to version 156.0.8078.47 or later to address the use after free vulnerability in PerformanceAPIs.
