In the Linux kernel the following vulnerability has been resolved:

RDMA/rxe: Fix the warning __rxe_cleanup+0x12c/0x170 [rdma_rxe]\n The Call Trace is as below: \n ? show_regs.cold+0x1a/0x1f ? __rxe_cleanup+0x12c/0x170 [rdma_rxe] ? __warn+0x84/0xd0 ? __rxe_cleanup+0x12c/0x170 [rdma_rxe] ? report_bug+0x105/0x180 ? handle_bug+0x46/0x80 ? exc_invalid_op+0x19/0x70 ? asm_exc_invalid_op+0x1b/0x20 ? __rxe_cleanup+0x12c/0x170 [rdma_rxe] ? __rxe_cleanup+0x124/0x170 [rdma_rxe] rxe_destroy_qp.cold+0x24/0x29 [rdma_rxe] ib_destroy_qp_user+0x118/0x190 [ib_core] rdma_destroy_qp.cold+0x43/0x5e [rdma_cm] rtrs_cq_qp_destroy.cold+0x1d/0x2b [rtrs_core] rtrs_srv_close_work.cold+0x1b/0x31 [rtrs_server] process_one_work+0x21d/0x3f0 worker_thread+0x4a/0x3c0 ? process_one_work+0x3f0/0x3f0 kthread+0xf0/0x120 ? kthread_complete_and_exit+0x20/0x20 ret_from_fork+0x22/0x30 \nWhen too many rdma resources are allocated rxe needs more time to handle these rdma resources. Sometimes with the current timeout rxe can not release the rdma resources correctly.

Compared with other rdma drivers a bigger timeout is used.
