CVSS 3.1
5.5 mediumCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2021-47345
Medium (5.5) in linux linux kernel. EPSS 0.3% chance of exploitation in the next 30 days.
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.
