Android patch level September 1, 2017 and later should contain the necessary patches for vulnerabilities related to BlueBorne. Given the recent monthly release cycle of updates then we should be seeing it soon. Verizon has been pushing out the security updates to customers in the 4th week of the month. I expect to see the latest update pushed out sometime after September 23rd. I'd figure around the 25th but that's just guessing.
As of September 28, 2017 Verizon is pushing out the latest update (NRD90M.G930VVRU4BQH4) for the Galaxy S7 in my area. On the positive side it deals with a number of issues. On the downside, I'm left perplexed. The update does not bumped the security patch level to September 1, 2017. We're left at August 1, 2017. AFAIK this also means that BlueBorne has not been dealt with.
Note: Nice to see they have corrected the update page with the proper software version. Previously they had reversed the versions between the S7 and S7 Edge.
