Pool.sol#L407-L413
The MultiSourceLoan contract calls the validateOffer() function to verify that the loan term has been approved by the Pool contract. This function also draws the necessary capital from the base interest allocator to ensure a sufficient balance for the loan.
As the pools balance includes capital awaiting claim by the queues, it needs to verify that the pool has enough capital to fund the loan. If this isnt the case, and the principal exceeds the current balance, the function needs to reallocate part of it.
However, the reallocate() function for the LidoEthBaseInterestAllocator performs a swap that could cause slippage. This could result in the contract still not having enough balance to provide the loan, even after calling reallocate().
