platform: Use acpi_bus_get_primary_device()","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nACPI: platform: Use acpi_bus_get_primary_device()\n\nThe acpi_get_first_physical_node() usage in acpi_platform_fill_resource()\nand acpi_create_platform_device() is generally unsafe because in theory\nthe device returned by it may be freed at any time [1].\n\nIt is also inefficient because acpi_get_first_physical_node() is called\nmultiple times for the same argument which can be avoided.\n\nAddress these issues by using acpi_bus_get_primary_device() instead of\nacpi_get_first_physical_node() and adjusting the code to call it just\nonce at the beginning of and acpi_create_platform_device() and drop\nthe device reference acquired by it upon the return from that function.","state":0,"publishedAt":"2026-09-25T13:06:45.579+00:00","modifiedAt":"2026-10-21T12:38:45.183+00:00","affected":[{"ecosystem":"Vendor
