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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Sync component of Google Chrome versions before 151.0.7922.72. 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.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 151.0.7922.72. To detect it, check your Chrome version by running chrome://version/ in the browser address bar. If the version is below 151.0.7922.72, the system is vulnerable. Update Chrome to the latest version to mitigate the risk.

Impact Analysis

An attacker could exploit this by tricking a user into visiting a specially crafted HTML page, potentially allowing them to execute arbitrary code within a sandboxed environment. This could lead to unauthorized access or control over the affected system.

Compliance Impact

This vulnerability is a use-after-free issue in Google Chrome's Sync component, enabling arbitrary code execution within a sandbox via a crafted HTML page. While it does not directly impact compliance with GDPR, HIPAA, or similar regulations, such vulnerabilities could potentially lead to unauthorized data access or processing, which may violate data protection requirements if exploited.

Mitigation Strategies

Update Google Chrome to version 151.0.7922.72 or later to address the use-after-free vulnerability in Sync.
