Heap buffer overflow in WebRTC in Google Chrome prior to 146.0.7680.153 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Heap buffer overflow in Google Chrome's WebRTC component (versions prior to 146.0.7680.153) enables remote code execution when users visit a malicious webpage, requiring only user interaction to trigger the vulnerability. An attacker can exploit this heap corruption to execute arbitrary code with the privileges of the affected browser process. A patch is available for Chrome and affected Linux distributions including Ubuntu and Debian.
Technical ContextAI
The vulnerability is a heap buffer overflow (CWE-122) in WebRTC, a real-time communication protocol implementation within Chrome's codebase. WebRTC handles media streaming and peer-to-peer connections; improper bounds checking during buffer operations in this component allows an attacker to write beyond allocated heap memory boundaries. This type of memory corruption can lead to disclosure of sensitive information, denial of service, or arbitrary code execution depending on exploitation technique and heap state. The affected product is Google Chrome (likely CPE: cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*), with all versions below 146.0.7680.153 confirmed vulnerable per EUVD tracking data.
RemediationAI
Users should immediately update Google Chrome to version 146.0.7680.153 or later via Settings > About Chrome, which will auto-download and apply the patch. Organizations deploying Chrome should use Google Admin Console or equivalent enterprise update mechanisms to force deployment of patched versions; updates typically require a browser restart but no system reboot. For Debian-based systems, update the chromium or google-chrome package via apt-get update && apt-get upgrade once the patched version reaches the distribution's repositories. Until patching is complete, consider restricting untrusted website access via network allowlists or DNS filtering, though this is not a robust substitute for patching a remote vulnerability. Enterprise environments should prioritize patching Chrome as the attack vector (remote, crafted HTML) requires only that a user visit a malicious or compromised website.
