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

  - f2fs: fix missing read bio submission on large folio error f2fs_read_data_large_folio() can keep a read     bio across multiple readahead folios. If a later folio hits an error before any of its blocks are added to     the bio, folio_in_bio is false and the current error path returns immediately after ending that folio.
    This can leave the bio accumulated for earlier folios unsubmitted. Those folios then never receive read     completion, and readers can wait indefinitely on the locked folios. Route errors through the common out     path so any pending bio is submitted before returning. Stop consuming more readahead folios once an error     is seen, and only wait on and clear the current folio when it was actually added to the bio.
    (CVE-2026-63820)
