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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 WebRTC within Google Chrome versions before 155.0.8059.39. A use-after-free occurs when a program continues to use memory after it 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.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 155.0.8059.39. Detection involves checking the installed Chrome version. On Linux, run: google-chrome --version. On Windows, check via 'Programs and Features' or run: wmic product where name='Google Chrome' get version. If the version is below 155.0.8059.39, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow a remote attacker to execute arbitrary code on your system. Since it occurs inside the Chrome sandbox, the impact is limited to the browser's security context. However, this could still lead to data theft, malware installation, or unauthorized actions within the browser.

Compliance Impact

This vulnerability allows remote code execution inside the sandbox via a crafted HTML page, which could lead to unauthorized access to sensitive data. This may impact compliance with GDPR by risking data breaches and HIPAA by potentially exposing protected health information.

Mitigation Strategies

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