What it is

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

RDMA/rvt: Return NULL after port allocation failure

rvt_alloc_device() deallocates the IB device when its port array cannot

be allocated but then returns the pointer to the released allocation.

Callers treat any non-NULL value as valid and dereference it, resulting

in a use-after-free.

Return NULL immediately after deallocation so callers can propagate the

allocation failure.
