# CVE-2024-4761: Google Chromium V8 Out-of-Bounds Memory Write 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 V8. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-05-16, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-06-06 ; treat that as the outer limit, not the target.
- EPSS 11.0% , percentile 96: FIRST’s model estimates a 11.0% chance of exploitation activity in the next 30 days, higher than 96% of all scored CVEs (very high). 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

Out of bounds write in V8 in Google Chrome prior to 124.0.6367.207 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: High)

## Affected products (CVE record)

- Google Chrome: 124.0.6367.207 < 124.0.6367.207

## Severity

- CISA-ADP CVSS 3.1: 8.3 `CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: added 2024-05-16; federal due date 2024-06-06. 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): 11.01% probability of exploitation activity in the next 30 days; percentile 96.
