CVE-2026-17784 is a use-after-free vulnerability (CWE-416) in the Audio subsystem of Google Chrome on Mac platforms before version 151.0.7922.72. The vulnerability enables a remote attacker, who has compromised the renderer process, to potentially perform a sandbox escape via a crafted HTML page. This could lead to increased privileges or further system compromise. The vulnerability is noted as medium severity by Chromium security, but no CVSS score or patch details are available in the provided data.

If exploited, this vulnerability could allow an attacker with control over the renderer process to escape the Chrome sandbox on Mac systems, potentially leading to execution of arbitrary code with higher privileges. However, exploitation requires prior compromise of the renderer process. No known exploits are reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should monitor official Google Chrome security advisories for updates and apply the official fix once available. Until then, limiting renderer process compromise risk is advisable.
