Red Hat Videos created a nice 3-minutes long clip that illustrates how the new Speculative Store Buffer Bypass (aka Spectre Variant 4) CPU vulnerability works. Patches from AMD and Intel are ready, and are expected to be rolled out soon.
Speculative Store Buffer Bypass is a security vulnerability that allows unauthorized users to steal sensitive information through websites. Similar to the Spectre and Meltdown threats in early 2018, it exploits speculative execution--a process most computers use to speed up routine tasks.
