Should you be worried? Probably not. In the whitepaper, the researchers did note that "AMD's design decisions indeed limit the exploitability scope" when compared to Meltdown-style attack vectors affecting Intel's CPUs, "yet it may be possible to use them to amplify other microarchitectural attacks."

Additionally, AMD's mitigation is for software vendors to review their code for any possible security holes related to this, adding that "potential vulnerabilities can be addressed by inserting an LFENCE or using existing speculation mitigation techniques."

On the user side of things, it sounds like the best thing to be done is to stay up to date with the latest patches.
