CVE-2021-47345 Information

Description

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 dma_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.
