CVE-2026-43313 ACPI: processor: Fix NULL-pointer dereference in acpi_processor_errata_piix4()

In the Linux kernel, the following vulnerability has been resolved: ACPI: processor: Fix NULL-pointer dereference in acpiprocessorerratapiix4 In acpiprocessorerratapiix4, the pointer dev is first assigned an IDE device and then reassigned an ISA device: dev = pcigetsubsys...,...

CVE-2026-43313

CVE-2026-43313 relates to a NULL-pointer dereference in the ACPI processor driver (acpi_processor_errata_piix4) of the Linux kernel. The code first assigns an IDE device to dev, then overwrites it with an ISA device using two successive pci_get_subsys lookups. If the first lookup succeeds but the...
