  "details": "In the Linux kernel, the following vulnerability has been resolved:  RDMA/irdma: Prevent user-triggered null deref on QP create  Previously, the user QP creation path would only attempt to populate iwqp-\u003eiwpbl if the user-provided req.user_wqe_bufs field was non-zero. The problem is that iwqp-\u003eiwpbl is unconditionally dereferenced later on in irdma_setup_virt_qp.  While there was a check for iwqp-\u003eiwpbl != NULL, this check would only occur if req.user_wqe_bufs was non-zero. The end result is that a user could send a zero user_wqe_bufs value and trigger a null ptr deref.  Fix this by unconditionally calling irdma_get_pbl and bailing if it fails, similar to the CQ and SRQ paths.",
