ReVault Flaw Exposed Millions of Dell Laptops to Malicious Domination

ReVault is a set of vulnerabilities in the Control Vault (unified secure hub) firmware found in millions of Dell Latitude and Precision business laptops; undocumented user-accessible APIs let local users send commands that can cause memory corruption, enable code execution on the secure chip, extract secret keys, alter firmware persistently (surviving OS reinstall), and bypass biometric authentication. Broadcom produced firmware fixes and Dell distributed patches via Windows updates, highlighting risks from embedded, undocumented firmware components.
