⚡ TL;DR | Go Straight to the Intel June 2021 Platform Update Vulnerabilities Audit.

CVE-2020-24489 – Intel VT-d Products

One of the highest-scoring vulnerabilities with a CVSS Base Score of 8.8 is a vulnerability in the Intel Virtualization Technology for Directed I/0 (VT-d) products. This can lead to local escalation of privilege on machines affected which is, unfortunately, quite the list. You can find it in the Intel-sa-00442 advisory.

In addition to this vulnerability, 3 more advisories were released covering fixes for a wide range of Intel processors (listed as sa-00463, sa-00464, and sa-00465). These include a BIOS firmware vulnerability which can lead to escalation of privilege or denial of service, Improper isolation of shared resources of processors and a domain-bypass transient execution vulnerability in Atom processors.

Since most modern CPUs and some older ones fall under one of these vulnerabilities, it is best you check if your vendors have updates available. To get an overview of which processors are in your environment, you can simply use our processor information report.
