CVE-2026-26315 Â (opens in a new tab)How to fix?
Upgrade github.com/ethereum/go-ethereum/crypto/ecies to version 1.16.9 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure in the GenerateShared() function in ecies.go. An attacker can extract bits of the p2p node key during an RLPx handshake by sending a series of malicious ephemeral public keys and inferring the validity of bits based on the incidence of ErrInvalidMessage returned.
Note: After upgrading to a fixed version, rotating the node key is recommended. This can be done by removing the file <datadir>/geth/nodekey.
