    Theoretically it should, since Android is using random Linux kernel versions that have never been updated in years.

    The big question is if ARM processors are vulnerable to this exploit at all, Cortex-A72 and Cortex-A57 and newer ARM are all using speculative execution so COULD be vulnerable in theory, older ones are using in-order execution so they cannot be vulnerable to this.

      You can't get a secure processor with good performance. It's more a question of time and money to identify possible attack vectors for different architectures.

        Not at all. But some *fools* might say that.

          Lol, AMD is also vulnerable to Spectre. AMD fanboys just like bragging about how their CPU is bigger than everyone else's, and thus deny reality.

            Your QoL will improve if you ignore people who can't read something as simple as Wikipedia.

              Performance impact on AMD with Spectre mitigations is 7%-ish vs. 30-50% for Intel with Meltdown+Spectre. And Intel knew all along that speculative execution without bounds checking would backfire badly, yet still implemented it anyway because every 1% counts when you're stuck on a process node.

              So yes, AMD is indeed more secure and way less retarded with their designs. It's just unfortunate tech companies are so incestuous and have to CLA with each other over (possibly) faulty technology.

                Sounds kinda advanced. And kinda evil. I'd say in all this race for speed at cheap prices something eventually got lost. Like, say, quality of implementation.
