CVE-2022-35936Network attack vector

Contract interruption via shared bytecode deletion

Published Aug 5, 2022 · Updated Apr 22, 2025

Denial of service in Evmos Ethermint 0.17.2 and earlier allows remote attackers to interrupt contracts sharing identical bytecode. DeleteAccount removes the single CodeHash-to-bytecode database entry during SELFDESTRUCT without tracking whether other contract instances still reference it. Exploitation requires deploying matching bytecode and invoking SELFDESTRUCT; transactions against every contract sharing that code then fail.
