Google Chrome: Use-after-free in Video component allows code execution
Summary
A use-after-free vulnerability in the Video component of Google Chrome desktop allows a remote attacker to execute arbitrary code inside the browser sandbox. The attacker must lure a user to a crafted HTML page, and no account is required. Chromium rates the severity as High, no exploitation has been reported, and a sandbox escape has not been confirmed.

Our recommendation
- Update all Google Chrome desktop installations to 156.0.8078.73 or later.
