Summary
Minting large amount of tokens through ibc transfer and then depositing them in validator rewards pool (via DepositValidatorRewardsPool message) can lead to integer overflow panic when calculating cumulative_reward_ratio for the validator.
This calculation happens in x/epoching module EndBlocker, thus the panic will halt the chain.
Impact
Denial of Service - Due to panic in the EndBlocker Babylon Genesis will halt
