Description

In the Linux kernel, the following vulnerability has been resolved:

netfs: release readahead folios on iterator preparation failure

netfs_prepare_read_iterator() batches readahead folios in put_batch so that the folio references can be dropped after the I/O iterator has been prepared.

If rolling_buffer_load_from_ra() fails after earlier folios have been batched, the function returns immediately and leaves those references held. Release the batch before returning the error.
