Virtualization is not emulation. An emulator (like WINE) makes use of a software bridge to simulate a different hardware environment, with a high cost in performance; software running on an emulator interacts with the bridge, not directly with the hardware. Software running in a Parallels VM runs directly on the native hardware at native, or near native, speeds. On a Mac running Apple Silicon, you create an native Arm VM with Parallels and you install an Arm version of Linux in the VM. There is no emulation.

So you find one that does (e.g., Kali and, soon, Fedora), easy-peasy. It’s also super easy to compile the latest and greatest source yourself under Linux (not that that’s everyone’s cup o’ tea).

Well, I admit that I didn’t say so explicitly, but I wasn’t really suggesting that one purchase and install Parallels just to fix the bug (which hopefully is going to be fixed soon — though if it isn’t, it won’t be Stephan’s fault, it will be due to some deeper problem with MacOS). I was assuming that one might have Parallels installed already or have independent reasons for purchasing it. For such folks, the VM solution (even if temporary) seems to me to be a reasonable one.

Hope it makes at least a bit of sense to you now. ;-)
