Research direction
Start by locating the cromfs code containing the file_info typedef and its buff allocation. Trace how the buffer is used for files larger than available memory, then define and validate a strategy that avoids allocating the entire file at once while preserving cromfs behavior. The issue names no specific tests or validation commands.
