New Spectre variants reportedly affect all Intel and AMD chips

Researchers have discovered multiple new variants of the Spectre exploits, affecting both Intel and AMD processors, that are not protected by existing mitigations.

Discovered by researchers from the University of Virginia and University of California San Diego, the vulnerabilities leak data via micro-op caches, which are meant to speed up processing by storing simple commands and allowing the processor to fetch them quickly and early in the speculative execution process.
