Description
In the Linux kernel, the following vulnerability has been resolved:
mcb: fix error handling in mcb_alloc_bus()
There are two bugs:
- If ida_simple_get() fails then this code calls put_device(carrier)
but we haven’t yet called get_device(carrier) and probably that
leads to a use after free.
- After device_initialize() then we need to use put_device() to
release the bus. This will free the internal resources tied to the
device and call mcb_free_bus() which will free the rest.
