Analysis

AI-generated

Technical impact

A use‑after‑free bug in the network component of Google Chrome allows a remote attacker to execute arbitrary code by delivering a crafted HTML page. The flaw is classified as CWE‑416 (Use‑After‑Free) and CWE‑825 (Incorrect Resource Management), and is rated critical in Chromium’s internal severity scale, indicating that exploitation can lead to full system compromise, including data theft and lateral movement.

Affected Systems

All installations of Google Chrome up to version 149.0.7827.53 on Windows, macOS, and Linux are affected. Any machine that runs one of these versions and visits the web is potentially exposed.

Risk and Exploitability

The CVSS score of 8.8 signifies a high severity. The EPSS score of <1% points to a very low current exploitation probability, but the flaw remains available for remote exploitation via malicious web content. The vulnerability is not listed in the CISA KEV catalog. Attackers most likely trigger the flaw by navigating to or loading a compromised web page that contains specially crafted content. Organizations with high exposure should treat this risk as immediate and act quickly.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply Chrome update 149.0.7827.53 or newer on all machines to patch the vulnerability.
  • If an update cannot be applied immediately, enforce a strict Content Security Policy on internal web applications to block external scripts and reduce exposure to crafted HTML.
  • Configure Chrome Enterprise policies or network gateways to block or filter traffic from known malicious domains until the patch is applied.
  • Monitor browser logs for unusual crashes or memory issues and alert on patterns consistent with use‑after‑free exploitation attempts.
