Ma compréhension mais je ne mets pas ma tête sur le billot
j’ en reste à ce commentaire concernant les cpu AMD
Yes, they are, although just by Spectre as far as we know (i.e. not
affected by Meltdown).
le changement de microcode ne concerne que Spectre, mais seulement pour Zen
grep bugs /proc/cpuinfo
bugs : tlb_mmatch fxsave_leak sysret_ss_attrs null_seg amd_e400

It seems AMD just released a microcode update to disable branch
prediction on its Zen architecture.

dmesg | grep "Kernel/User page tables isolation: enabled" && echo "patched :)" || echo "unpatched :("
unpatched :(
l’update du noyau concerne Meltdown donc seulement Intel
