Researchers develop SafeSpec to overcome vulnerabilities like Spectre and Meltdown

Computer scientists from the University of California, the College of William and Mary, and Binghamton University have published a paper detailing a new "design principle" that avoids speculative execution vulnerabilities. Researchers says that the SafeSpec model supports "speculation in a way that is immune to the sidechannel leakage necessary for attacks such as Meltdown and Spectre". Importantly, the design also avoids the problems associated with other Meltdown/Spectre fixes.
