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

  - f2fs: fix to do sanity check on destination blkaddr during recovery As Wenqing Liu reported in bugzilla:

This patch introduces a new flag     DATA_GENERIC_ENHANCE_UPDATE, w/ this flag, data block recovery flow can check destination blkaddr's     validation in SIT table, and skip f2fs_replace_block() to avoid inconsistent status. (CVE-2022-50273)

Note that Nessus relies on the presence of the package as reported by the vendor.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-992745 advisory.
