The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper control over consumption of internal resources. A remote attacker can connect to the affected AP as a client and send a high rate of traffic over an extended period of time, which will result in an overuse of AP resources and denial of service.
