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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 the Compositing component of Google Chrome. It occurs when a program continues to use memory after it has been freed, potentially leading to arbitrary code execution within the browser's sandbox. The issue is triggered by a crafted HTML page and affects Chrome versions prior to 155.0.8059.84.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 155.0.8059.84. Detection involves checking the installed Chrome version. On Windows, Linux, or macOS, open Chrome and go to chrome://settings/help to see if an update is available. If the version is below 155.0.8059.84, the system is vulnerable.

Impact Analysis

This vulnerability could allow a remote attacker to execute malicious code on your system through a specially designed webpage. Since it occurs within the sandbox, the attacker's code would be limited to the browser's environment, reducing but not eliminating the risk of system compromise.

Compliance Impact

This vulnerability is a use-after-free issue in Google Chrome's Compositing feature, enabling remote code execution within the sandbox. Such vulnerabilities could potentially lead to unauthorized data access or manipulation, which may impact compliance with GDPR (data protection) or HIPAA (healthcare data privacy) if exploited.

Mitigation Strategies

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