CVE-2021-47345
Red Hat Linux RDMA Memory Leak Vulnerability
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 "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.
