Question about Spectre vulnerability mitigation

Post by rkhunter » Fri Jan 12, 2018 6:58 pm

Guys, I have little question about Spectre#1 mitigation in Win10 kernel.

For what Win10 kernel trap handlers were updated with LFENCE instructions? As I understand Spectre#1 can't allow Ring 3 code to read kernel memory or to be executed as Ring 0. Or I'm wrong?
