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

  - idpf: bound interrupt-vector register fill to the allocated array idpf_get_reg_intr_vecs() fills the     caller-allocated reg_vals[] array from the VIRTCHNL2_OP_ALLOC_VECTORS reply in adapter->req_vec_chunks,     bounding its inner loop only by the per-chunk num_vectors. The array is sized separately:
    idpf_intr_reg_init() allocates kzalloc_objs(struct idpf_vec_regs, total_vecs) from     caps.num_allocated_vectors and only checks the returned count after the fill. The sum of per-chunk     num_vectors is never reconciled against total_vecs, so a reply with a small num_allocated_vectors but     chunks summing higher writes past the end of reg_vals[]. Impact: a control plane (a PF or hypervisor     device model) that returns a VIRTCHNL2_OP_ALLOC_VECTORS reply whose per-chunk num_vectors sum exceeds     num_allocated_vectors writes struct idpf_vec_regs entries past the end of the reg_vals kmalloc allocation     (KASAN slab-out-of-bounds write). Bound the fill loop to the array capacity passed in by the callers,     mirroring the sibling idpf_vport_get_q_reg(). The existing num_regs < num_vecs check then rejects an     undersized reply without the out-of-bounds write happening first. (CVE-2026-80693)

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