Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 在 Linux 内核中，已解决以下漏洞： iommu/vt-d: Fix potential memory leak in intel_setup_irq_remapping() After commit e3beca48a45b (irqdomain/treewide: Keep firmware node unconditionally allocated). For tear down scenario, fn is only freed after fail to allocate ir_domain, though it also should be freed in case dmar_enable_qi returns error. Besides free fn, irq_domain and ir_msi_domain need to be removed as well if intel_setup_irq_remapping fails to enable queued invalidation.
    Improve the rewinding path by add out_free_ir_domain and out_free_fwnode lables per Baolu's suggestion.
    (CVE-2022-48724)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
