⚡ TL;DR | Go Straight to the Dell BIOS SMM Vulnerabilities Report

DSA-2022-053: Multiple SMM Vulnerabilities

Dell recently released a new security advisory covering 5 new vulnerabilities in the System Management Mode (SMM) of multiple of their models including Alienware, Inspiron, Vostro, and XPS. All 5 of the vulnerabilities got a CVSS base score of 8.2 and “Dell recommends all customers update at the earliest opportunity“.

Attackers that can successfully exploit the vulnerability could potentially execute code on the system. SMM code that is executed is always executing using the highest privilege level while also being undetectable by the operating system, this potent combination makes this vulnerability an ideal candidate for deploying malicious firmware to affected devices that would lead to more severe issues down the road.
