Thanks for reply, we have many deployments with 220.127.116.11, 18.104.22.168, 22.214.171.124 in production, as per bug it seems only 126.96.36.199 is affected, do i still need to go for upgrade ?
All the versions you've mentioned are affected. Wait for Cisco to release the software fix and upgrade.
Remember, the problem is not just at the AP-end. Both APs and wireless clients need to be patched. Patching the client will fix 9 out of 10 vulnerabilities but not CVE-2017-13082.
