CVE-2026-26315 High · 7.5 CWE-203 Feb 19, 2026
Go Ethereum Improperly Validates the ECIES Public Key in RLPx Handshake
go-ethereum (Geth) is a golang execution layer implementation of the Ethereum protocol. Prior to version 1.16.9, through a flaw in the ECIES cryptography implementation, an attacker may be able to extract bits of the p2p node key. The issue is resolved in the v1.16.9 and v1.17.0 releases of Geth. Geth maintainers recommend rotating the node key after applying the upgrade, which can be done by removing the file `<datadir>/geth/nodekey` before starting Geth.
CVE-2026-26314 High · 7.5 CWE-20 Feb 19, 2026
Go Ethereum affected by DoS via malicious p2p message
go-ethereum (geth) is a golang execution layer implementation of the Ethereum protocol. Prior to version 1.16.9, a vulnerable node can be forced to shutdown/crash using a specially crafted message. The problem is resolved in the v1.16.9 and v1.17.0 releases of Geth.
