CVE-2021-47392

Summary: CVE-2021-47392 concerns a leak in the Linux kernel RDMA CMA listener path. If rdma_cma_listen_on_all() fails, the per-device ID remains on the listen_list, but the state is not set to RDMA_CM_ADDR_BOUND. When the CMID is later destroyed, cma_cancel_listens() may not be invoked due to the...

CVE-2021-47391 RDMA/cma: Ensure rdma_addr_cancel() happens before issuing more requests

In the Linux kernel, the following vulnerability has been resolved: RDMA/cma: Ensure rdmaaddrcancel happens before issuing more requests The FSM can run in a circle allowing rdmaresolveip to be called twice on the same idpriv. While this cannot happen without going through the work, it violates t...
