The previous investigations into these attacks have been a little ad hoc in nature: examining particular features of interest to provide, for example, a Spectre attack that can be performed remotely over a network or Meltdown-esque attack to break into SGX enclaves. The new research is more systematic, looking at the underlying mechanisms behind both Meltdown and Spectre and running through all the different ways the speculative execution can be misdirected.In a statement, Intel explains current mitigation techniques for Spectre and Meltdown fully address these new vulnerabilities.
Seven more Spectre/Meltdown-like vulnerabilities discovered

A team of researchers, including many of the original researchers that discovered Meltdown and Spectre, announce the discovery of seven more speculative execution bugs. Most of the attacks concern Intel processors, but AMD and ARM-based CPUs are also vulnerable to some variants. ARS Technica has all the details over here.
