March 5, 2022 (updated September 2, 2026)

A design flaw in Go-Ethereum 1.10.12 and older versions allows an attacker node to send 5120 future transactions with a high gas price in one message, which can purge all of pending transactions in a victim node’s memory pool, causing a denial of service (DoS).
