Contract state manipulation via premature substate commit
Published Jan 2, 2024 · Updated Jun 17, 2025
Improper exception handling in rust-ethereum Rust EVM before 0.41.1 allows remote attackers to commit unexpected contract state changes. CREATE and CREATE2 finalization commits the successful substate before calling the fallible record_external_operation write hook, so a later callback error reaches the parent after the commit. Exposure requires a library consumer whose custom hook returns an error; the parent receives a zero address while the completed contract execution has already altered state.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
