Looking At The LVI Mitigation Impact On Intel Cascade Lake Refresh
On Friday I posted some initial numbers looking at the LVI mitigation impact when using the LLVM Clang compiler with that open-source, multi-platform compiler having landed its mitigation this week for Intel's Load Value Injection (LVI) vulnerability that was disclosed in March. Through the weekend I have been running some additional tests of this compiler-based mitigation and in this article are some numbers off Cascade Lake Refresh, which while recently released is reported by Intel to still be vulnerable to this new disclosure.
