Dan Carpenter 91e4ad05bf mcb: fix error handling in mcb_alloc_bus() ... commit 25a1433216489de4abc889910f744e952cb6dbae upstream. There are two bugs: 1) 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. 2) 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. Fixes: 5d9e2ab9fe ("mcb: Implement bus->dev.release callback") Fixes: 18d2881980 ("mcb: Correctly initialize the bus's device") Cc: stable@vger.kernel.org Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Johannes Thumshirn <jth@kernel.org> Link: https://lore.kernel.org/r/32e160cf6864ce77f9d62948338e24db9fd8ead9.1630931319.git.johannes.thumshirn@wdc.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2021-09-30 10:11:00 +02:00
