CVE-2021-47001

In CVE-2021-47001, the Linux kernel’s rpcrdma path (net/sunrpc/xprtrdma/rpc_rdma.c) has a race in cwnd update ordering after reconnects, where the reply handler may open the cwnd before rpcrdma_post_recvs() posts enough Receive WEs, causing an RNR and immediate connection loss. This race is highl...
