CVE-2026-13951 is a vulnerability in Google Chrome affecting versions before 150.0.7871.47. It involves insufficient policy enforcement in the USB subsystem, which could allow a remote attacker with control over the renderer process to perform a sandbox escape by delivering a crafted HTML page. This could undermine the browser's security sandbox protections. The vulnerability is rated medium severity by the Chromium security team. No explicit patch or remediation level is stated in the provided data, but a vendor advisory is linked for updates.

If exploited, this vulnerability could allow an attacker who has already compromised the renderer process to escape the sandbox environment, potentially gaining higher privileges or access to the underlying system. This increases the risk of further system compromise beyond the browser sandbox. However, exploitation requires prior compromise of the renderer process and crafted content delivery.
