Analysis

AI-generated

Technical impact

A use‑after‑free flaw in Chrome’s Safebrowsing component on macOS lets a remote attacker execute arbitrary code outside the browser sandbox by loading a specially crafted HTML page. The vulnerability can be triggered via social engineering, granting the attacker full control of the victim’s machine and compromising confidentiality, integrity, and availability.

Affected Systems

Google Chrome running on macOS versions earlier than 152.0.7977.65 are affected. The bug exists in the Safebrowsing feature and impacts all users of that version.

Risk and Exploitability

Chromium categorizes the issue as Critical, with a CVSS score of 9.6 and an EPSS score of not available. The flaw is remotely exploitable through a web page; a malicious site can deliver the crafted content. No known public exploits are documented and the vulnerability is not listed in the CISA KEV catalog. Given the critical severity, the risk remains high until affected browsers are updated.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade all macOS installations of Google Chrome to version 152.0.7977.65 or later to resolve the use‑after‑free bug.
  • Restrict users from opening untrusted HTML content by blocking access to suspicious sites and providing training on social engineering tactics.
  • Enable Chrome’s auto‑update feature or schedule regular manual updates to ensure new patches are applied promptly.
