Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

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

  - wifi: rtw89: pci: configure manual DAC mode via PCI config API only To support 36-bit DMA, configure chip     proprietary bit via PCI config API or chip DBI interface. However, the PCI device mmap isn't set yet and     the DBI is also inaccessible via mmap, so only if the bit can be accessible via PCI config API, chip can     support 36-bit DMA. Otherwise, fallback to 32-bit DMA. With NULL mmap address, kernel throws trace: BUG:

  - wifirtw89pci僅透過 PCI config API 設定手動 DAC 模式。若要支援 36 位元 DMA請透過 PCI config API 或晶片 DBI 介面設定晶片專屬位元。但是尚未設定 PCI 裝置 mmap且 DBI 也無法透過 mmap 存取因此只有在可透過 PCI config API 存取該位元時晶片才能支援 36 位元 DMA。否則遞補至 32 位元 DMA。在 NULL mmap 位址的情況下核心會擲回追踪錯誤
