    These new multiple unfixable hardware M1 & A14 flaws are yet more
    evidence that Apple has never designed a best-in-class SOC in its
    entire history.

    Sorry, but you claim these AREN'T Apple's designs, remember?

    Besides which, it's not actually an Apple flaw. It's a flaw in *all* ARM chips.

    I hadn't read that. Got a link?

    Why answer it? Just encourages it to post blather again and again ...

    Notice how ignorant the iKooks are that there are _multiple_ (*different!*) unpatchable flaws we've been talking about since the start of this thread.

    They think there's just one flaw and that it only affects one Apple SOC.
    How wrong they (always) are indeed!

    For the few _adults_ on this newsgroup, what would be a useful set of facts would be to list which Apple chips are affected by these _multiple_ flaws.
    a. PAC (pointer authentication codes)
    b. M1racles CVE-2021-30747
    At least one of which gives the attacker full control of the machine
    under exploitable circumstances (which is why they shouldn't be there).

    An adult question is to ask which Apple SOCs are affected by these flaws:
    1. We know the M1 has at least _two_ different unpatchable hardware flaws.
    2. We are told the PAC flaws are likely also in the M1 Pro and M1 Max.
    3. We also know the A14 is affected by at least this most recent H/W flaw.
    4. And we know the M2 uses a "similar" (if not the same) PAC flow design.

    What other Apple SOCs are affected by these _multiple_ hardware flaws? Specifically, does anyone know about the vaunted A15 hardware design?

    Note that the iKooks are always shockingly completely ignorant.
    A. They're unaware of the hardware flaws found about a year ago
    B. And they're ignorant of the different new hardware flaws found now.

    Yet the fact-based question deserves an answer so that we know which Apple SOCs are affected by these _multiple_ (different!) unpatchable hardware flaws.

    Only an actual adult can answer that fact-based question correctly.

    According you, there are not "Apple SOCs" and that there is only marketing.
