Analyze CVE-2026-95310 with Vani AIImpact, affected versions, exploitation status, mitigations and detection

A use-after-free flaw (CWE-416) in the AdFilter component of Google Chrome, in versions prior to 154.0.8037.57, lets a remote attacker run arbitrary code outside the browser sandbox. The issue is triggered when a user opens a crafted HTML page. Chromium rates the bug Critical because successful exploitation breaks out of the sandbox rather than staying inside the renderer. Anyone still running an unpatched Chrome build older than 154.0.8037.57 is affected. No public proof of concept is known, the CVE is not on CISA’s Known Exploited Vulnerabilities list, and CVSS has not yet been scored, so exploitation in the wild is not currently known.

What to do: Update Google Chrome to version 154.0.8037.57 or later and fully restart the browser so the update is applied. Confirm the running build under chrome://settings/help, and apply the same Chromium-based vendor updates if your environment tracks this Chrome release.
