远程主机上安装的 F5 Networks BIG-IP 版本低于测试版本。因此，它受到 K000163557 公告中提及的一个漏洞影响。

    在 Linux 内核中，以下漏洞已修复：ACPI: processor: Fix NULL-pointer dereference in acpi_processor_errata_piix4() In acpi_processor_errata_piix4(), the pointer dev is first assigned an IDE device and then reassigned an ISA device: dev = pci_get_subsys(..., PCI_DEVICE_ID_INTEL_82371AB, ...); dev = pci_get_subsys(..., PCI_DEVICE_ID_INTEL_82371AB_0, ...); If the first lookup succeeds but the second fails, dev becomes NULL. This leads to a potential null-pointer dereference when dev_dbg() is called: if (errata.piix4.bmisx) dev_dbg(&dev->dev, ...); To prevent this, use two temporary pointers and retrieve each device independently, avoiding overwriting dev with a possible NULL value. [ rjw: Subject adjustment, added an empty code line ](CVE-2026-43313)

Tenable 直接从 F5 Networks BIG-IP 安全公告中提取了前面的描述块。

请注意，Nessus 尚未测试此问题，而是只依据应用程序自我报告的版本号进行判断。
