If you own a Dell laptop especially a Precision, Latitude, or Pro model, there’s a new security issue you should know about. Security researchers have uncovered five serious flaws in the Broadcom BCM5820X chips that power Dell’s ControlVault3 feature. These chips are built into more than 100 different Dell models, putting millions of laptops in homes and businesses at risk.
ControlVault3 is designed to act as a digital vault for your most sensitive information, including passwords, biometric data, and encryption keys. But these newly discovered vulnerabilities, now known as “ReVault,” undermine that trust. The flaws, identified as CVE-2025-24311, CVE-2025-25215, CVE-2025-24922, CVE-2025-25050, and CVE-2025-24919, each target a different part of the ControlVault3 firmware and its Windows APIs. Together, they create several paths for attackers to get in and take control.
If someone exploits these vulnerabilities, the consequences go far beyond data theft. Attackers could run malicious code on your laptop from anywhere in the world, bypass your password or fingerprint login, and even change the firmware so that any fingerprint unlocks your device. In some cases, malware can be installed at the firmware level, which means it would survive even if you completely reinstall Windows. This kind of persistent access is extremely difficult to detect or remove.
The technical details behind these flaws are complex, but the bottom line is that attackers can leak information, overwrite protected memory, and run code that should never be allowed. Because ControlVault3 is meant to protect your most sensitive data, a successful attack could expose passwords, biometric data, and security codes. In the worst case, an attacker could take full control of your laptop and bypass all the usual security checks.
There are a few ways these exploits can be triggered. Attackers might use malware or a low-privilege account to interact with ControlVault APIs and gain higher access. If they have physical access to your laptop, they could connect directly to the Unified Security Hub inside the device and tamper with the firmware. Once inside, they can install malware that stays put even after a full system wipe, making it very hard to remove.
Dell responded quickly after learning about these issues. The company worked with its firmware provider to release security updates and published a detailed advisory (DSA-2025-053) with a list of affected models and instructions for updating. Dell strongly recommends all users update their devices as soon as possible. You can find updates on Dell’s support site or through the Dell Command Center.
If you own a Dell Precision, Latitude, or Pro laptop, check if your device is affected and install the latest updates right away. In high-risk situations, it’s a good idea to turn off fingerprint login until your device is patched.
This incident is a reminder that even hardware-based security features can have flaws. Keeping your firmware and drivers up to date is just as important as updating your operating system or antivirus software. When the hardware is vulnerable, the risks go far beyond what software security can fix.
