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

  - exfat: fix double free in delayed_free The double free could happen in the following path.
    exfat_create_upcase_table() exfat_create_upcase_table() : return error exfat_free_upcase_table() : free
    ->vol_utbl exfat_load_default_upcase_table : return error exfat_kill_sb() delayed_free()     exfat_free_upcase_table() <--------- double free This patch set ->vol_util as NULL after freeing it.
    (CVE-2025-38206)

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