CSCvf47808 - Key Reinstallation attacks against WPA protocol - 10

[mohdshiraj1]

Hi 

After upgrading from 8.2.141.0 to 8.3.130.0 we are facing issue with mobile connection to AP.

On new version some mobile is connected and some not able to connect.

now we have reverted back to old version and it is working fine

Any idea or new version is having any bugs.

Kindly delay with doing any upgrade to 8.3.131.0. During their testing phase (after the release) they found some issues affecting non-Wave 2 APs. They've found what the issue is and they're testing the new fix before releasing the fix version on 23 October 2017.
I have updated my earlier post of the ETA of the fix to reflect the new development.

Software fix for the KRACK vulnerability is now available for download. They are 8.0.152.0, 8.2.164.0, 8.3.132.0 and 8.5.105.0.

A quick update to anyone reading this thread and intending to upgrade to 8.3.132.0:
Cisco TAC has recommended anyone to HOLD OFF upgrading to 8.3.132.0. TAC has identified a Severity 1 bug which causes the controller to crash after upgrading to 8.3.132.0.
There are no reported issues in regards to other versions.
