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

RDMA/cma: Fix rdma_resolve_route() memory leak

Fix a memory leak when "mda_resolve_route() is called more than once on
the same "rdma_cm_id".

This is possible if cma_query_handler() triggers the
RDMA_CM_EVENT_ROUTE_ERROR flow which puts the state machine back and
allows rdma_resolve_route() to be called again.
