The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - f2fs: only redirty pinned folios in redirty_blocks redirty_blocks() pins folios with read_cache_folio()     and then walks the same range again with filemap_lock_folio() to redirty them and drop the references it     took. Commit 5951fee46bef (f2fs: Use a folio in redirty_blocks()) changed the second pass to a do/while     loop. If read_cache_folio() fails before anything is pinned, page_idx does not advance but the cleanup     loop still runs once. If readahead has already populated the failed folio in page cache, that extra     iteration finds it and folio_put_refs(folio, 2) drops one reference too many. Later drop_caches or reclaim     can then report BUG: Bad page state. Only redirty the range that was pinned successfully.
    (CVE-2026-89841)
