CVE-2022-23328 · HIGH Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

A design flaw in all versions of Go-Ethereum allows an attacker node to send 5120 pending transactions of a high gas price from one account that all fully spend the full balance of the account to a victim Geth node, which can purge all of pending transactions in a victim node's memory pool and then occupy the memory pool to prevent new transactions from entering the pool, resulting in a denial of service (DoS).
