7 more speculative execution attacks

Wed Nov 14, 2018 2:22 am

A research team—including many of the original researchers behind Meltdown, Spectre, and the related Foreshadow and BranchScope attacks—has published a new paper disclosing yet more attacks in the Spectre and Meltdown families. The result? Seven new possible attacks. Some are mitigated by known mitigation techniques, but others are not. That means further work is required to safeguard vulnerable systems.

Does this mean Intel will have to go to a one-core-per-thread ratio?

The more I think about it, the less I like virtual cores. They remind me of rice cakes. Or styrofoam cakes.

Oh, and I wonder also...will single-concurrent-user personal computer users be forced to apply yet more performance-degrading BIOS and Windows updates to address these issues that are not likely to impact us?
