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

  - Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause     the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the     operating system user running the database. In applications that pass gigabyte-scale user inputs to the     relevant database functions, the application input provider may achieve a segmentation fault. Versions     before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected. (CVE-2026-6473)

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