Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 已解決 Linux 核心中的下列弱點：iommu: Don't reserve 0-length IOVA region When the bootloader/firmware doesn't setup the framebuffers, their address and size are 0 in iommu-addresses property. If IOVA region is reserved with 0 length, then it ends up corrupting the IOVA rbtree with an entry which has pfn_hi < pfn_lo. If we intend to use display driver in kernel without framebuffer then it's causing the display IOMMU mappings to fail as entire valid IOVA space is reserved when address and length are passed as 0. An ideal solution would be firmware removing the iommu-addresses property and corresponding memory-region if display is not present. But the kernel should be able to handle this by checking for size of IOVA region and skipping the IOVA reservation if size is 0.
    Also, add a warning if firmware is requesting 0-length IOVA region reservation. (CVE-2023-52455)

請注意，Nessus 依賴供應商報告的套件存在。
