Technical Description
In the Linux kernel, the following vulnerability has been resolved:
xprtrdma: Fix ep kref imbalance on ADDR_CHANGE
rpcrdma_cm_event_handler() falls through to the disconnected: label
on RDMA_CM_EVENT_ADDR_CHANGE and calls rpcrdma_ep_put() with no
matching get when the event arrives before RDMA_CM_EVENT_ESTABLISHED.
The kref then underflows during connect teardown and
rpcrdma_xprt_disconnect() operates on a freed ep.
Reference counts across a normal connection lifecycle:
rpcrdma_ep_create() kref_init ->1
rpcrdma_xprt_connect() ep_get ->2 (before post_recvs)
RDMA_CM_EVENT_ESTABLISHED ep_get ->3
RDMA_CM_EVENT_DISCONNECTED ep_put ->2
rpcrdma_xprt_drain() ep_put ->1
rpcrdma_xprt_disconnect() tail ep_put ->0 (ep_destroy)
The connect-time get in rpcrdma_xprt_connect(), taken just before
rpcrdma_post_recvs() "while there are outstanding Receives," is
balanced by rpcrdma_xprt_drain.
