In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Prevent handling any completions after qp destroy HW may generate completions that indicates QP is destroyed. Driver should not be scheduling any more completion handlers for this QP, after the QP is destroyed. Since CQs are active during the QP destroy, driver may still schedule completion handlers. This can cause a race where the destroy_cq and poll_cq running simultaneously. Snippet of kernel panic while doing bnxt_re driver load unload in loop. This indicates a poll after the CQ is freed.  [77786.481636] Call Trace: [77786.481640]  <TASK> [77786.481644]  bnxt_re_poll_cq+0x14a/0x620 [bnxt_re] [77786.481658]  ? kvm_clock_read+0x14/0x30 [77786.481693]  __ib_process_cq+0x57/0x190 [ib_core] [77786.481728]  ib_cq_poll_work+0x26/0x80 [ib_core] [77786.481761]  process_one_work+0x1e5/0x3f0 [77786.481768]  worker_thread+0x50/0x3a0 [77786.481785]  ? __pfx_worker_thread+0x10/0x10 [77786.481790]  ...
