Exploit públicoNo conocidosin código público localizado
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:
wifi: mac80211: exigir una estación par para la confirmación de configuración de TDLS
No tiene sentido que la confirmación de configuración vaya a una estación que ni siquiera existe, y eso provoca una advertencia al construir la trama:
Solo se acepta WLAN_TDLS_SETUP_CONFIRM cuando la estación ya existe como estación TDLS. Es necesario copiar la llamada a ieee80211_tdls_prep_mgmt_packet() ya que WLAN_TDLS_DISCOVERY_REQUEST existente ya pasa a través de ella.
