# rebalance() in glAVAX reverts if currentReserves == reserveTarget Low/Info · Three Sigma · Liquid staking · 12th July, 2023 Finding 3S-GLACIER-L04 of the Glacier security review. - Protocol: https://www.glacier.io/ - Report: /reports/glacier - Source: https://cdn.sanity.io/files/qoqld077/production/21bd3b6fa78c55968a6c9c7ea4fd49f34a8bd3d8.pdf --- ### Description [rebalance()](https://github.com/JackFrostDev/glacier-contracts/blob/main/contracts/protocol/GlacialAVAX/glAVAX.sol#L314) in glAVAX deposits to the ReservePool if there is available liquidity (balance) and the currentReserves are smaller than the reserveTarget. The problem is that the ReservePool reverts when trying to [withdraw 0](https://github.com/JackFrostDev/glacier-contracts/blob/main/contracts/protocol/ReservePool/GReservePool.sol#L192), which is the case if currentReserves == reserveTarget. ### Status Currently being reviewed by the team. --- Related findings: - [ClampLib::mulDivDownInverse reverts on `target == type(uint256).max` before the overflow guard runs](https://0xsimao.com/findings/tenor-markets-reverts-overflow-guard-runs): Tenor Morpho Migrations
