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

  - f2fs: validate compress cache inode only when enabled F2FS_COMPRESS_INO() uses NM_I(sbi)->max_nid as the     synthetic inode number for the compressed page cache inode. That inode only exists when the compress_cache     mount option is enabled. When compress_cache is disabled, max_nid is outside the valid inode range. A     corrupted directory entry that points to ino == max_nid should therefore be rejected by     f2fs_check_nid_range(). However, is_meta_ino() currently treats F2FS_COMPRESS_INO() as a meta inode     unconditionally, so f2fs_iget() bypasses do_read_inode() and its nid range check, and instantiates a fake     internal inode instead. Gate the compressed cache inode case on COMPRESS_CACHE, matching     f2fs_init_compress_inode(). With compress_cache disabled, ino == max_nid now follows the normal inode path     and is rejected as an out-of-range nid. (CVE-2026-63817)

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