exfat_find_free_bitmap() searches the entire allocation bitmap and may wrap around to its beginning. exfat_trim_fs() does not verify that the returned cluster is still within the requested FITRIM range. As a result, a partial FITRIM operation may discard free clusters outside the user-specified range and report a trimmed length larger than the requested length. Validate each returned cluster against the requested range and stop the search when it wraps around or passes the range end.
