wait, so does this mean that if an exploit tries to use a 32 bit address it's immediately shut down?

  There are usually no valid 32 bit addresses, i.e. the first 4GB are not mapped.

    That might be their point. As the OP quoted > any virtual address below 0x100, 000, 000 is invalid. That kinda suggests that all 32bit addresses are inherently invalid on 64bit MacOS

      Not inherently, it's just a linker default. You can run 32-bit processes through WINE.

        Only in Rosetta. On arm64 these binaries will not be allowed to load.
