In the Linux kernel, the following vulnerability has been resolved: RDMA/mana: Remove user triggerable WARN_ON() in mana_ib_create_qp_rss() Sashiko points out that the user can specify WQs sharing the same CQ as a part of the uAPI and this will trigger the WARN_ON() then go on to corrupt the kernel. Just reject it outright and fail the QP creation.
