Millions of Dell laptops at risk due to Broadcom chip security flaw - here's how you can stay safe

• Critical security vulnerabilities have been identified in Broadcom chips
• These flaws leave Dell devices containing the chips at risk
• The resulting attack has been dubbed 'ReVault', and users should patch now

A host of critical security flaws in Broadcom chips could mean tens of millions of Dell laptops and other devices are at risk of possible attack.

The serious vulnerabilities have been found in over 100 models of Dell laptops with Broadcom chips, Cisco Talos has revealed, and are therefore at risk of an attack the researchers dubbed ‘ReVault’.

A ReVault attack could be used ‘as a physical compromise to bypass Windows Login and/or for any local user to gain Admin/System privileges’, allowing a hacker to steal sensitive information and credentials, as well as biometric data like fingerprint information.
