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

  - btrfs: free mapping node on duplicate reloc root insert __add_reloc_root() allocates a mapping_node before     inserting it into rc->reloc_root_tree. If rb_simple_insert() finds an existing entry, it returns the     existing rb_node and leaves the newly allocated node unlinked. The error path then returns -EEXIST without     freeing the new node. Since the node was never inserted into reloc_root_tree, the later cleanup in     put_reloc_control() cannot find it either. Free the newly allocated node before returning -EEXIST. The     callers currently assert that -EEXIST should not happen, so this is a defensive cleanup for an unexpected     duplicate insert path. If the path is ever reached, the local allocation should still be released.
    (CVE-2026-68450)

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