# CVE-2023-7024: Google Chromium WebRTC Heap Buffer Overflow Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Google Chromium WebRTC. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-01-02, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-01-23 ; treat that as the outer limit, not the target.
- EPSS 6.7% , percentile 94: FIRST’s model estimates a 6.7% chance of exploitation activity in the next 30 days, higher than 94% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.

## What it is

Heap buffer overflow in WebRTC in Google Chrome prior to 120.0.6099.129 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

## Affected products (CVE record)

- Google Chrome: 120.0.6099.129 < 120.0.6099.129

## Severity

- CISA-ADP CVSS 3.1: 8.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: added 2024-01-02; federal due date 2024-01-23. Known ransomware use: Unknown.
- CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
- CISA SSVC assessment: exploitation active , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 6.67% probability of exploitation activity in the next 30 days; percentile 94.
