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

  - gve: DQO: reject TSO packets with an out of range MSS gve_prep_tso() notes that the device requires the     MSS to be <= 9728, but does not enforce it, assuming the 9K MTU enforced by the hypervisor and the 64KB     limit on TSO sizes are enough. This does not hold for packets that were not generated locally. A guest     behind a tap, or any packet socket user, can provide an arbitrary gso_size in virtio_net_hdr. Layer 2     forwarding does not check the MTU for GSO packets (is_skb_forwardable()), and gso_features_check() only     bounds skb->len and gso_segs, never gso_size. Such a packet reaches gve_tx_fill_tso_ctx_desc(), which puts     gso_size into the mss field of the TSO context descriptor. This field is 14 bits wide, so a gso_size of     16384 is silently turned into an MSS of zero. Drop these packets from gve_prep_tso(), and make sure that     gve_features_check_dqo() leaves their GSO bits alone: skb_segment() splits at gso_size regardless of the     MTU, so falling back to software segmentation would give the device non TSO packets bigger than the 9728     bytes it supports. Note that the device can still be given oversized non TSO packets when the stack     segments in software for other reasons, for instance after TSO has been disabled with ethtool. This is a     generic issue, because the MTU check is skipped for GSO packets in the forwarding path, and is addressed     separately. (CVE-2026-98556)

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