QID 981200

QID 981200: Go (go) Security Update for github.com/ethereum/go-ethereum (GHSA-9856-9gg9-qcmq)

A memory-corruption bug within the EVM can cause a consensus error, where vulnerable nodes obtain a different `stateRoot` when processing a maliciously crafted transaction. This, in turn, would lead to the chain being split in two forks.

All Geth versions supporting the London hard fork are vulnerable (which predates London), so all users should update.

This bug was exploited on Mainnet at block 13107518, leading to a minority chain split.

A vulnerability in the Geth EVM could cause a node to reject the canonical chain.
