An exploitable denial-of-service vulnerability exists in the Linux kernel. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker within radio range can forge Authentication and Association Request packets to trigger this vulnerability.
