Title

RDMA/rxe: Fix unsafe drain work queue code

Summary

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix unsafe drain work queue code If create_qp does not fully succeed it is possible for qp cleanup code to attempt to drain the send or recv work queues before the queues have been created causing a seg fault. This patch checks to see if the queues exist before attempting to drain them.

Severity

5.5 (Medium)
