Intel started 2018 with an unfortunate bang — the Spectre and Meltdown flaws inherent in the architecture of their chips was the main topic of conversation in the cybersecurity world. While damage control continues regarding those vulnerabilities, another flaw has been flagged. Intel refers to the new flaw as Level 1 Terminal Fault, or L1TF, but security researchers have dubbed it something more colorful — Foreshadow, and it is present in Intel Core processors and Xeon chips.
