Do you think this could be within the rather new Intel AVX 512 ISA or older intel CPUs like Sandy Bridge (first AVX chip) could also suffer?
- edit - I checked Ryzen ISA, they support AVX2. So probably AVX512 is the issue.

[1] I do hope they rename that flag to something like X86_BUG_NEEDS_PTI as the current name is bloody abysmal: way too broad and ambiguous, as if this is the only insecurity that ever has or ever will impact x86.
