Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA/efa: Fix wrong resources deallocation order<br /> <br /> When trying to destroy QP or CQ, we first decrease the refcount and<br /> potentially free memory regions allocated for the object and then<br /> request the device to destroy the object. If the device fails, the<br /> object isn&amp;#39;t fully destroyed so the user/IB core can try to destroy the<br /> object again which will lead to underflow when trying to decrease an<br /> already zeroed refcount.<br /> <br /> Deallocate resources in reverse order of allocating them to safely free<br /> them.
