Since I believe this is a Intel chip problem, is it needed in an AMD system?

my understanding is no

dolphin_oracle,

From what I have read, this mediation of the Zombieload problem can be a performance hit on some functions in a Mac operating system performance, and 20-30% in MS windows. I have not seen the performance hit # for Linux, but there must be some o/s slowdown to fix this hardware problem for Intel Processors.

Understand the latest Intel CPUs are not effected by Zombieload (Gen 8 and 9)

neither are the original generations of the core architecture. anything before sandy bridge should be ok if I'm reading things correctly.

[namida12]

However a great number of Intel users are not using the latest generation of processors and I believe anticapitalista suggestions are correct, until user upgrade their hardware/computer.

Living in Vegas, I would bet there are other hardware exploitable flaws that are known at the highest levels that have still not been published/disclosed to the general computer users.

Not according to the kernel developers.

From my AMD laptop:

Code: Select all

E485:~$ cat /sys/devices/system/cpu/vulnerabilities/mds
Not affected
E485:~$

I put the 5.1.2 on and if my mobile broadband continues to function will stay with it.
