Security researchers have discovered multiple serious flaws in Dell’s ControlVault3 system that could allow hackers to bypass login on certain laptops.
The issues, named ReVault, affect the firmware that handles secure login features like fingerprint scans and smartcard authentication on Dell Latitude and Precision models.
The flaws give attackers with physical access a way to take control of the device. They could install malware that remains even after reinstalling Windows or gain full access without needing a password. The bugs include memory-related problems and issues with how the system processes data, which make it easier for attackers to run their own code on the device.
Experts warn that these vulnerabilities are particularly dangerous because they target the part of the system meant to keep login information safe. Dell has released updates to fix the problem across more than 100 laptop models.
Users are strongly advised to install the latest firmware and drivers to protect their devices from being exploited.
