Description
The vulnerability allows an attacker to perform spoofing attack.
The vulnerability exists due to insufficient verification of data authenticity in mesh networks using Wi-Fi Protected Access (WPA, WPA2, or WPA3) or Wired Equivalent Privacy (WEP). A remote attacker on the local network can inject arbitrary frames towards devices that support receiving non-SSP A-MSDU frames and perform spoofing attack.
