This is quoted directly from Armis' website, which is the security company that found several vulnerabilities including "Blueborne"[1]:
The vulnerabilities disclosed by Armis
affect all devices running on Android,
Linux, Windows, and pre-version 10 of
iOS operating systems, regardless of
the Bluetooth version in use.
There has been no mention of finding firmware issues with the LE peer device in their report[2], and the list of vulnerabilities are directly related to classic bluetooth (except section "Apple’s LEAP - RCE in Apple’s Low Energy Audio Protocol - CVE-2017-14315", which is a overflow vulnerability in a specific service in iOS 9 and lower).
