CVE-2026-80897: Linux

EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux: from 6.14, before 6.18.44 (fixed in 6.18.44); from 6.19, before 7.1.8 (fixed in 7.1.8)
