CVE-2026-28522: NULL Pointer Dereference

arduino-TuyaOpen before version 1.2.1 contains a null pointer dereference vulnerability in the WiFiUDP component. An attacker on the same local area network can send a large volume of malicious UDP packets that trigger a null pointer dereference, resulting in a denial-of-service condition...
