An improper access control flaw in Chrome's V8 JavaScript engine lets a remote attacker read browser memory by getting a user to visit a crafted HTML page. No authentication beyond page load is required. Successful exploitation can expose sensitive process memory to the attacker. Chrome releases before 156.0.8078.73 are affected.

What to do: Update Chrome to version 156.0.8078.73 or later; Chrome's auto-update should apply the fix after relaunch.
