CVE-2026-100072

In the Linux kernel, the following vulnerability has been resolved:

ACPI: platform: Use acpi_bus_get_primary_device()

The acpi_get_first_physical_node() usage in acpi_platform_fill_resource()
and acpi_create_platform_device() is generally unsafe because in theory
the device returned by it may be freed at any time [1]. It is also inefficient because acpi_get_first_physical_node() is called
multiple times for the same argument which can be avoided. Address these issues by using acpi_bus_get_primary_device() instead of
acpi_get_first_physical_node() and adjusting the code to call it just
once at the beginning of and acpi_create_platform_device() and drop
the device reference acquired by it upon the return from that function.
