On August 6, 2025, Dell Inc. issued an emergency security advisory (numbered DSA-2025-053), highlighting that a large number of its PCs are at serious cybersecurity risk due to vulnerabilities in Broadcom chips. The main devices affected are Dell Precision and Latitude laptops equipped with Broadcom's BCM5820X series chips. These devices are widely used in business settings and are also employed by some individual users.

Vulnerability Details

There are five high-risk vulnerabilities in the relevant chips, specifically numbered CVE-2025-24311, CVE-2025-25215, CVE-2025-24922, CVE-2025-25050, and CVE-2025-24919. All these vulnerabilities involve the ControlVault3 feature built into the chip, which is a hardware-based mechanism for storing sensitive information in the firmware, such as passwords and biometric data. According to data from the U.S. National Vulnerability Database (NVD), attackers can exploit these vulnerabilities through carefully crafted ControlVault3 APIs to steal information, arbitrarily release memory, execute code remotely, and write data to out-of-bounds memory locations. With CVSS scores all above 8.0, these vulnerabilities are marked as "high-risk," which is also the main reason Dell has set the update level to "critical."

Impact Scope and Response Measures

Although there is no evidence yet that the vulnerabilities have been exploited in reality, given the widespread use of Dell Precision and Latitude laptops in business environments, it is estimated that the number of affected PCs could reach tens of millions. Dell said that relevant customers were privately informed of the existence of the vulnerabilities as early as June 13. Currently, patches for the ControlVault3 driver and firmware have been released. A Dell spokesperson emphasized that customers should promptly install the security updates provided by Dell and upgrade to supported product versions to ensure the security of their systems.
