Description
The vulnerability allows an adjacent attacker to force a supplicant that is compliant with the 802.11z standard to reinstall a previously used TPK key.
The weakness exists in the processing of the 802.11z (Extensions to Direct-Link Setup) TDLS handshake messages due to ambiguities in the processing of associated protocol messages. An adjacent attacker can passively eavesdrop on a TDLS handshake and retransmit previously used message exchanges between supplicant and authenticator.
