Impact

A use‑after‑free flaw in WebRTC allows a remote attacker to execute arbitrary code inside Chrome’s sandbox when a crafted HTML page is loaded. The vulnerability, identified as CWE‑416 and CWE‑825, can lead to manipulation of the browser process and compromise of the sandboxed execution context.

Affected Systems

Google Chrome versions earlier than 149.0.7827.53 on desktop platforms are affected. The flaw impacts all operating systems where the desktop browser runs, providing a universal attack surface for users of earlier releases.

Risk and Exploitability

The EPSS score for this issue is 0.00071, indicating a very low likelihood of exploitation, and the vulnerability is not listed in CISA’s KEV catalog. The CVSS score is 8.8, indicating a high severity; the Chromium documentation rates the severity as Medium, reflecting a serious flaw. The likely attack vector involves a remote attacker controlling the content of a web page that a victim visits; the crafted HTML triggers the use‑after‑free while the browser is rendering the page.

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update Chrome to version 149.0.7827.53 or newer.
  • If an update cannot be installed immediately, disable WebRTC via the browser’s settings or a policy setting to prevent the vulnerable code from executing.
  • For environments that cannot update or disable WebRTC, reduce the user’s privileges for Chrome or run the browser in a sandboxed user account to limit potential damage.
