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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 prior to 152.0.7977.75. 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 and execute arbitrary code inside the browser's sandbox.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 152.0.7977.75. 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 152.0.7977.75, the system is vulnerable.

Impact Analysis

If you use an affected version of Google Chrome, this vulnerability could allow a remote attacker to run malicious code on your system. Since the exploit occurs via a crafted HTML page, simply visiting a malicious website could trigger the issue. The sandbox limits the impact, but successful exploitation could still lead to unauthorized code execution or data compromise.

Compliance Impact

The provided CVE data does not specify direct impacts on compliance with standards like GDPR or HIPAA. The vulnerability involves a use-after-free issue in WebRTC in Google Chrome, which could allow remote code execution. However, without additional context on data exposure or processing, its compliance impact remains unclear.

Mitigation Strategies

Update Google Chrome to version 152.0.7977.75 or later to address the use after free vulnerability in WebRTC.
