So...what’s the risk? Will my speakers spontaneously start to play polka or something?
Cynical me says this is a good way to get people off their ‘old crap’ and update/buy new as WE are not going to waste our time protecting the older models.
Way back when ‘they’ invented the bugs, ‘we’ were told that there was no way certain things could be tracked so don’t worry about the ‘government’ tracking you and there is no way we can find all those students who overstayed their visas.
A ‘bug’ popped up and within 24 hours it was traced to a seedy hotel in a Manila suburb.
A cow in Montana was suspected of having ‘Mad Cow Disease’ and within 24 hours they had a print out of the cows lineage back to his great great great great grandfather.
More likely some Russian folk song...

That’s risk enough right there.
Your devices can spread ransom wear, fail to work until you pay the ransom, steal your data, access your bank accounts if that data is on them, infect other bluetooth devices that come into their vicinity, including those belonging to friends if they are vulnerable, and then continue the infection further. Bluetooth is used for the Internet of Things, including the new keyless door locking systems, cars, etc. All of them could be infected if they are vulnerable.
