"The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2024-56785 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: MIPS: Loongson64: DTS: Really fix PCIe
    port nodes for ls7a Fix the dtc warnings: arch/mips/boot/dts/loongson/ls7a-pch.dtsi:68.16-416.5: Warning
    (interrupt_provider): /bus@10000000/pci@1a000000: '#interrupt-cells' found, but node is not an interrupt
    provider arch/mips/boot/dts/loongson/ls7a-pch.dtsi:68.16-416.5: Warning (interrupt_provider):
    /bus@10000000/pci@1a000000: '#interrupt-cells' found, but node is not an interrupt provider
    arch/mips/boot/dts/loongson/loongson64g_4core_ls7a.dtb: Warning (interrupt_map): Failed prerequisite
    'interrupt_provider' And a runtime warning introduced in commit 045b14ca5c36 (of: WARN on deprecated
    #address-cells/#size-cells handling): WARNING: CPU: 0 PID: 1 at drivers/of/base.c:106
    of_bus_n_addr_cells+0x9c/0xe0 Missing '#address-cells' in /bus@10000000/pci@1a000000/pci_bridge@9,0 The
    fix is similar to commit d89a415ff8d5 (MIPS: Loongson64: DTS: Fix PCIe port nodes for ls7a), which has
    fixed the issue for ls2k (despite its subject mentions ls7a). (CVE-2024-56785)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
