Description A vulnerability in 802.11 association request frame processing could allow an unauthenticated, Layer 2 radio frequency (RF) adjacent attacker to cause the Access Point (AP) to reload, resulting in a denial of service (DoS) condition. The issue is due to insufficient frame validation of the 802.11 association request. An attacker could exploit this by sending a malformed 802.11 association request to the targeted device, allowing them to cause the AP to reload and resulting in a DoS condition while the AP is reloading.
