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

  - LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. From 1.6.51 to 1.6.53, there is a heap buffer over-read in the     libpng simplified API function png_image_finish_read when processing interlaced 16-bit PNGs with 8-bit     output format and non-minimal row stride. This is a regression introduced by the fix for CVE-2025-65018.
    This vulnerability is fixed in 1.6.54. (CVE-2026-22695)

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