# Heap buffer overflow in WebRTC in Google Chrome prior to 120.0.6099.129 allowed a remote attacker to potentially…

A heap buffer overflow in the WebRTC component of Chromium lets a remote attacker corrupt heap memory by getting a victim to load a crafted HTML page. Exploitation in the wild is confirmed by CISA's KEV catalog.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Google Chromium WebRTC affected ? fixed ?
- vendor:google chrome affected < 120.0.6099.129 fixed 120.0.6099.129
- vendor:debian linux affected = 11.0 fixed ?
- vendor:debian linux affected = 12.0 fixed ?
- vendor:fedoraproject fedora affected = 38 fixed ?
- vendor:fedoraproject fedora affected = 39 fixed ?

## Fix

Update Google Chrome and other Chromium-based browsers to a release that includes the vendor's fix; the sources do not name the fixed version.

## From the sources

Google Chromium WebRTC, an open-source project providing web browsers with real-time communication, contains a heap buffer overflow vulnerability that allows a remote attacker to potentially exploit heap corruption via a crafted HTML page. This vulnerability could impact web browsers using WebRTC, including but not limited to Google Chrome.

CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
