Description
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.
