"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/mana_ib: drain QP references after partial table insertion\n\nmana_table_store_ud_qp() publishes a QP at its send-queue id before\ninserting the receive-queue id, dropping the XArray lock between the two\nxa_insert_irq() calls. A concurrent completion handler can look up the QP\nand take a transient reference. When the second insertion fails, the\nrollback erased only the send-queue entry and returned, leaving both the\ninitial table reference and the transient reference outstanding while RDMA\ncore frees the QP, causing a use-after-free.\n\nDrain the reference as normal destruction does: drop the initial reference\nand wait for qp->free, releasing the QP only after every concurrent lookup\nreturns its reference."
