CVE-2026-80897

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.
