Exploitability

CWE

KEV

CWE ID	Description
CWE-190	The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

Attack-Flow Graph

Executive Summary

This vulnerability is an integer overflow in WebRTC within Google Chrome versions before 152.0.7977.65. An attacker could exploit this by crafting a malicious HTML page to potentially execute arbitrary code inside the browser's sandbox.

Detection Guidance

This CVE describes an integer overflow in WebRTC within Google Chrome. Detection primarily involves checking the installed Chrome version. Use commands like 'google-chrome --version' or 'chromium-browser --version' to verify if your version is prior to 152.0.7977.65. If vulnerable, update Chrome immediately.

Impact Analysis

If exploited, this vulnerability could allow a remote attacker to run arbitrary code on your system through a specially designed webpage. However, the sandboxing in Chrome limits the impact, reducing the risk of full system compromise.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR, HIPAA, or similar standards as it involves a low-severity integer overflow in WebRTC within Google Chrome. Compliance risks would depend on specific implementation contexts rather than the vulnerability itself.

Mitigation Strategies

Update Google Chrome to version 152.0.7977.65 or later to address the integer overflow vulnerability in WebRTC.
