  3. CVE-2021-47345
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: RDMA/cma: Reparar pérdida de memoria rdma_resolve_route(). Reparar una pérdida de memoria cuando se llama a "mda_resolve_route() más de una vez en el mismo "rdma_cm_id". Esto es posible si cma_query_handler() desencadena el flujo RDMA_CM_EVENT_ROUTE_ERROR que devuelve la máquina de estado y permite volver a llamar a rdma_resolve_route().
