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。

  - 已修复 Linux 内核中的下列漏洞：PCI: rcar-host: Pass proper IRQ domain to generic_handle_domain_irq() Starting with commit dd26c1a23fd5 (PCI: rcar-host: Switch to msi_create_parent_irq_domain()), the MSI parent IRQ domain is NULL because the object of type struct irq_domain_info passed to: msi_create_parent_irq_domain() -> irq_domain_instantiate()() ->
    __irq_domain_instantiate() has no reference to the parent IRQ domain. Using msi->domain->parent as an argument for generic_handle_domain_irq() leads to below error: Unable to handle kernel NULL pointer dereference at virtual address This error was identified while switching the upcoming RZ/G3S PCIe host controller driver to msi_create_parent_irq_domain() (which was using a similar pattern to handle MSIs (see link section)), but it was not tested on hardware using the pcie-rcar-host controller driver due to lack of hardware. [mani: reworded subject and description] (CVE-2025-40076)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
