What is CVE-2019-12588?

The client implementation of 802.11 MAC layer in Espressif ESP8266_NONOS_SDK versions 2.2.0 to 3.1.0 is vulnerable due to improper validation of the RSN AuthKey suite list count found in beacon frames, probe responses, and association responses. This flaw enables attackers within radio range to send specially crafted messages, which can lead to a denial of service by crashing the device.
