Impact

A use‑after‑free flaw in the Chrome browser on macOS allows a remote attacker who lures a user to a crafted HTML page to execute code outside the browser sandbox. The flaw is triggered by malformed memory handling, enabling arbitrary code execution with system privileges once the corrupted pointer is dereferenced. The vulnerability is rated as high severity by Chromium due to its potential to compromise the entire system.

Affected Systems

Google Chrome browsers on macOS versions earlier than 151.0.7922.169 are affected. The issue does not extend to newer releases or to other operating systems listed.

Risk and Exploitability

No official CVSS score is provided, but Chromium rates the vulnerability as high severity. EPSS data is not available and it is not listed in the CISA KEV catalog. The flaw can be triggered via remote web content, requiring social engineering to lure a user to a crafted page. An unauthenticated attacker could obtain full system access if the flaw is triggered.
