"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nACPI: PCI: Clear driver_data on all paths that free the acpi_pci_root\n\nacpi_pci_root_add() assigns the freshly allocated root to\ndevice->driver_data before dmar_device_add() and pci_acpi_scan_root().\nBoth failure paths reach the end: label where root is kfree()'d, but\nonly the pci_acpi_scan_root() path clears driver_data first.\n\nWhen dmar_device_add() fails during a hot-add, root is freed while\ndevice->driver_data still points at it. The ACPI core does not clear\ndriver_data on attach failure, so a later acpi_pci_find_root() call may\ndereference this dangling pointer.\n\nacpi_pci_root_remove() has the same problem: it frees root without\nclearing device->driver_data, leaving a dangling pointer behind after\nthe root bridge is removed.\n\nMove the NULL assignment to the shared end: label so every error path in\nacpi_pci_root_add() clears driver_data before freeing root, and clear it\nin acpi_pci_root_remove() as well, so the object is never left reachable\nthrough driver_data after being freed."
