Vulnerability details

Impact

When referencing data, using memory is more expansive than using storage https://github.com/code-423n4/2021-11-vader/blob/main/contracts/tokens/vesting/LinearVesting.sol#L103,
this can happen because if you are referencing using a memory, it will copy the data to the memory, but in the storage pointer it will referencing the data directly from the storage.
