> Ok so given that this is a hardware flaw and not a software flaw is this kind of disclosure reasonable?
Yes. Always, always yes. Even if it's unfixable, ignorance of there even being a problem is not better.
> Is there anything analogous here for hardware?
Yes, actually. BIOS updates can include microcode updates and workarounds for hardware issues. Similarly if it takes a specific pattern to happen (which this almost certainly does as that's how these things work), that's going to be trivial for everyone's antivirus scanners to catch.
