So far no Intel security blog posts if there are any other security advisories this second Tuesday of the month outside of these three requiring the microcode updates. Onward to benchmarking the CPU microcode updates to see if there are any performance changes as a result. Officially known as the Intel 11th Gen Core processors, the new family of chips come in Core i3. Thus out now is a big batch of CPU microcode updates for Linux users with microcode-20210608. Intel’s Tiger Lake processors are now out in the wild, having been revealed fully on September 2. In this article, we want to take a look at the S-series product line to determine how. In addition to the Intel Core i3, i5, and i7 brands it turns out that there are actual two or three different product lines within each of those brands - including 'K', 'S', and 'T'. Intel SA-00465 - Intel Atom processors are vulnerable to information disclosure via a domain-bypass transient execution vulnerability. If you are in the market for a new PC, you have likely had a taste of the huge variety of different Intel CPU models available. These issues were found by external researchers. The issues stem from improper isolation of shared resources to observable timing discrepancies that could lead to information disclosure.

Intel SA-00464 - A set of multiple security vulnerabilities that could lead to information disclosure. This is due to an incomplete cleanup whereby authenticated users with local access could exploit to enable higher privileges. Intel SA-00442 - With a CVSS Base Score of 8.8 "High" is a new VT-d advisory where a vulnerability with Intel Virtualization Technology for Direct I/O could lead to a privilege escalation.
