This is one of the risks we take when we buy a 3rd party lens.
All electronic devices have to be made to appropriate standards, where they have some level of immunity to receiving interference, and they also must not generate excessive interference. Such testing will never cover every possible combination of use cases. It is possible to be in compliance and still encounter problems like the one described here.
If you had used Canon lens on Canon body, of course any problems will be with Canon. Here we have Tamron saying their lenses work on Canon. Canon do not say you can use Tamron lenses. Therefore I think this is up to Tamron to sort out in the first instance.
