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

  - In the Linux kernel, the following vulnerability has been resolved: vxlan: vnifilter: enforce exact length     of GROUP/GROUP6 attributes The VXLAN VNI filter entry policy declares the GROUP/GROUP6 address attributes     as NLA_BINARY with only a maximum length, so validate_nla() accepts a payload shorter than the address.
    The GROUP consumer reads it with nla_get_in_addr(), an unconditional 4-byte load, so a short attribute     over-reads up to 3 bytes of uninitialised slab data, which are stored into remote_ip and echoed back via     RTM_GETTUNNEL, disclosing kernel memory. Switch both entries to NLA_POLICY_EXACT_LEN() so the validator     rejects any GROUP/GROUP6 that is not exactly 4 / 16 bytes; a valid address is always sent at full width.
    (CVE-2026-89776)

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