Ping of death attack

The field length of an IP packet is 16 bits, and the maximum length of an IP packet is 65535. Therefore, if the data length of an ICMP request packet is larger than 65507, the entire length of the ICMP packet (ICMP data + IP header 20 + ICMP header 8) will be larger than 65535, which may make some devices or systems crash, die or reboot. This is the Ping of Death attack.
