GHSA-v592-xf75-856p is a medium-severity (CVSS 5.3) CWE-682 vulnerability in github.com/ethereum/go-ethereum. O3 Security confirms whether GHSA-v592-xf75-856p is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Erroneous Proof of Work calculation in geth
Real-World Exposure
github.com/ethereum/go-ethereumReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Impact
An ethash mining DAG generation flaw in Geth could cause miners to erroneously calculate PoW in an upcoming epoch (estimated early January, 2021). This happened on the ETC chain on 2020-11-06. This issue is relevant only for miners, non-mining nodes are unaffected.
Patches
This issue is also fixed as of 1.9.24. Thanks to @slavikus for bringing the issue to our attention and writing the fix.
Workarounds

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/ethereum/go-ethereum. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update github.com/ethereum/go-ethereum to 1.9.24 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v592-xf75-856p is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-v592-xf75-856p is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-v592-xf75-856p. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-v592-xf75-856p in your dependencies?
O3 detects GHSA-v592-xf75-856p across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
