Official description

In the Linux kernel, the following vulnerability has been resolved: ACPI: scan: fix bus ID cleanup on device_add() failures When device_add() fails after acpi_device_set_name() has allocated an instance ID and a new acpi_device_bus_id has been linked into acpi_bus_id_list, the rollback path only removes wakeup_list and detaches the ACPI handle data. That leaves the bus-ID bookkeeping behind and keeps the allocated instance number consumed. Move the bus-ID cleanup and wakeup-list removal into a single helper. Use it from both the normal device teardown path and the device_add() rollback path. The wakeup list node is initialized before registration, so it can be deleted without checking whether the device is wakeup- capable like in the original teardown path. [ rjw: Rename acpi_device_del_list() to acpi_device_cleanup() ] [ rjw: Subject and changelog edits ]
