Intel CPU Vulnerability
Commenters discuss a new CPU vulnerability primarily affecting Intel processors, mitigated through microcode updates, frequently comparing it to Spectre and Meltdown while debating AMD immunity and performance impacts.

At least it's fixed in microcode, unlike some recent exploits (Spectre and Meltdown come to mind)
Maybe it has something to do with Meltdown/Spectre mitigations.
well, for intel-cpu's i am not so sure how it might be possible, given all that is known after the spectre/meltdown fiasco.
It might be blindly applying all the Intel brokeness (spectre/meltdown) patches to AMD cpu.
Are these Intel-only bugs? AMD uses a different approach to speculative execution and claims that the Meltdown-type attack won't work on post-Bulldozer CPUs.
Intel claims [1] that they already have microcode mitigation. Like Spectre and Meltdown this is likely to have performance implications.[1] https://www.intel.com/content/www/us/en/security-center/advi...
Zen2 has hardware mitigations so "the same".
All Intel CPU's are affected, mitigation syscall overhead increased by 50%, and none of AMD CPU's affected? I would say this could be an indicator to short INTC and long AMD...
I guess this would help with Meltdown/Spectre type bugs.
Is it a coincidence that newer CPU's aren't vulnerable, or was it fixed because of discussions with Intel?
