CVE-2026-17804 is a use-after-free vulnerability in the Media component of Google Chrome before version 151.0.7922.72. An attacker who has compromised the renderer process could exploit this flaw to perform a sandbox escape by delivering a crafted HTML page. This vulnerability is related to improper memory management (use-after-free) and could lead to increased privileges within the browser sandbox environment.

If exploited, this vulnerability could allow an attacker with control over the renderer process to escape the sandbox protections of Google Chrome. This could lead to execution of code outside the restricted environment, potentially increasing the attacker's capabilities on the host system. However, exploitation requires prior compromise of the renderer process.
