Tailscale... accessible from where? It would likely require an attacker to jump from the endpoint to a vulnerable application (or SSH) which, while possible, seems improbable. Maybe over time as the exploit gets packaged in more suites, or if targeted personally.
On the VPS, check cpuinfo to see if it's one of the vulnerable ones. If it is, then I'd either ask them directly, avoid that kind of VPS for a while, or use it for non-sensitive stuff until it gets a fix.
ARM... will have its day. Speculative branching is too tempting to ignore, and too difficult to implement flawlessly. Just give them time 😉
