### Impact Setting lower EVM call gas allows users to partially execute precompiles and error at specific points in the precompile code without reverting the partially written state. If executed on the distribution precompile when claiming funds, it could cause funds to be transferred to a user without resetting the claimable rewards to 0. The vulnerability could also be used to cause indeterministic execution by failing at other points in the code, halting validators. Any evmOS or Cosmos EVM chain using precompiles is affected. ### Patches The vulnerability was patched by wrapping each precompile execution into an atomic function that reverts any partially committed state on error. - [evmos/os](https://github.com/evmos/os) patch file: https://drive.google.com/file/d/1LfC0WSrQOqwTOW3qfaE6t8Jqf1PLVtS_/ For chains using a different file structure, you must manually apply the diff: ### **In `x/evm/statedb.go`:** Add the following function: ```go func (s *StateDB) RevertMultiStore(...
