Summary
net/dibs: Correct freeing of dmb_clientid_arr
Details

In the Linux kernel, the following vulnerability has been resolved:

net/dibs: Correct freeing of dmb_clientid_arr

A dibs device interrupt handler can be active after dibs_dev_del() and may still access dmb_clientid_arr. (UAF)

In case of a failure in dibs_dev_add() being called by dibs_lo_dev_probe() dmb_clientid_arr is freed twice (double free).

Free dmb_clientid_arr in dibs_dev_release() after last reference is gone. Note that allocating in dibs_dev_add() instead of dibs_dev_alloc() is ok for now, because no dmbs can be registered before dibs_dev_add().
