Here comes another one….called PortSmash

A vulnerability called PortSmash or CVE-2018-5407 has joined the list of other dangerous side-channel vulnerabilities discovered in the past year, including older ones like Meltdown, Spectre and Foreshadow. This side channel vulnerability resides Intel’s Hyper-Threading technology. This vulnerability allows an attacker to see sensitive protected data like passwords and keys from other processes running in the same CPU core with simultaneous multi-threading feature enabled.

Will something like the T2 chip that apple makes on the Mac prevent issues like this?
