遠端主機上安裝的 F5 Networks BIG-IP 版本為測試版本之前的版本。因此，它會受到 K000163557 公告中提及的一個弱點影響。

    在 Linux 核心中，下列弱點已解決：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 已直接從 F5 Networks BIG-IP 安全公告中擷取前置描述區塊。

請注意，Nessus 並未測試此問題，而是僅依據應用程式自我報告的版本號碼作出判斷。
