There is no check if the return value indicates stale data. This could lead to stale prices according to the Chainlink documentation:
The price oracle might return unreliable price data which can lead to a variety of different issues in the protocol, for example, for liquidating more staker & lender tokens than required at fair market price.
Add missing checks for stale data. See example here.
