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

  - drm/amdgpu: zero-initialize GART table on allocation GART TLB is flushed after unmapping but not after     mapping. Since amdgpu_bo_create_kernel() does not zero-initialize the buffer, when a single PTE is written     the TLB may speculatively load other uninitialized entries from the same cacheline. Those garbage entries     can appear valid, and a subsequent write to another PTE in the same cacheline may cause the GPU to use a     stale garbage PTE from the TLB. Fix this by calling memset_io() to zero-initialize the GART table with     gart_pte_flags immediately after allocation. Using AMDGPU_GEM_CREATE_VRAM_CLEARED, SDMA-based clear will     not work since SDMA needs GART to be initialized to work. (cherry picked from commit     d9af8263b82b6eaa60c5718e0c6631c5037e4b24) (CVE-2026-53374)

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