Impact
Through a flaw in the ECIES cryptography implementation, an attacker may be able to extract bits of the p2p node key.
Patches
The issue is resolved in the v1.16.9 and v1.17.0 releases of Geth. We recommend rotating the node key after applying the upgrade, which can be done by removing the file <datadir>/geth/nodekey before starting Geth.
