Are 3700 AP's, running 5G only, safe from KRACK?

[poulid]

The KRACK advisory says this;

Further Problem Description:
Cisco wireless APs models 1570, 1700, 2700 and 3700 are NOT vulnerable for 5Ghz connections, but are vulnerable on 2.4Ghz connections.

Anyone know how that could be, or if it's even true?

This vulnerability affects anything with a wireless NIC.  It's not just wireless AP but also wireless clients as well.  Patching the client will fix 9 out of 10 vulnerabilities but not CVE-2017-13082.  This means that if you patch your APs and the client hasn't/won't patch their side, 9 vulnerabilities can be exploited against the client.  

Perspective About the Recent WPA Vulnerabilities (KRACK Attacks)

Cisco will be releasing software fix (see below) soon.
