RDMA/efa: Fix wrong resources deallocation order

AI Analysis

No AI analysis yet.

Description

In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Fix wrong resources deallocation order When trying to destroy QP or CQ, we first decrease the refcount and potentially free memory regions allocated for the object and then request the device to destroy the object. If the device fails, the object isn't fully destroyed so the user/IB core can try to destroy the object again which will lead to underflow when trying to decrease an already zeroed refcount. Deallocate resources in reverse order of allocating them to safely free them.
