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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Google Chrome's Track component. A use-after-free occurs when a program continues to use a pointer after freeing the memory it points to. In this case, a remote attacker could exploit this by crafting a malicious HTML page to execute arbitrary code within the browser's sandbox.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 155.0.8059.39. Detection involves checking the installed Chrome version. Use commands like 'google-chrome --version' on Linux or check 'chrome://settings/help' in the browser. If the version is below 155.0.8059.39, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your device through a specially designed webpage. Since it occurs in the sandbox, the attacker's code would be limited to the browser's environment, but could still steal data, install malware, or perform other harmful actions.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code inside the sandbox via crafted HTML pages. Such arbitrary code execution could lead to unauthorized data access, modification, or exfiltration, which may violate GDPR's data protection principles or HIPAA's security requirements for protected health information.

Mitigation Strategies

Update Google Chrome to version 155.0.8059.39 or later to address the use-after-free vulnerability in Track.
