"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nACPI: bus: Introduce acpi_bus_get_primary_device()\n\nThe function used for obtaining the first \"physical\" device for which\nthe given ACPI one is the ACPI companion, acpi_get_first_physical_node(),\nmay return a stale device pointer (mostly in theory) because\nacpi_unbind_one() may run as a whole after dropping the ACPI device's\nphysical_node_lock in acpi_get_first_physical_node() and before it\nreturns. The last reference to the \"physical\" device may be dropped\nthen before the pointer to it is returned to the caller.\n\nIf that happens and the acpi_get_first_physical_node() caller invokes\nget_device() on the pointer obtained from it, which is done by the\nmajority of its callers, a use-after-free will occur.\n\nTo prepare for addressing this problem, introduce a new function for\ngetting the first \"physical\" device associated with the given ACPI one\n(the \"primary physical device\") that will also reference count the\ndevice in question before returning a pointer to it.\n\nMake that new function and acpi_get_first_physical_node() share the\nphysical node list lookup code.\n\nNo intentional functional impact."
