"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/rxe: Fix BUG: KASAN: null-ptr-deref in rxe_qp_do_cleanup\n\nThe function rxe_create_qp calls rxe_qp_from_init. If some error\noccurs, the error handler of function rxe_qp_from_init will set\nboth scq and rcq to NULL.\n\nThen rxe_create_qp calls rxe_put to handle qp. In the end,\nrxe_qp_do_cleanup is called by rxe_put. rxe_qp_do_cleanup directly\naccesses scq and rcq before checking them. This will cause\nnull-ptr-deref error.\n\nThe call graph is as below:\n\nrxe_create_qp {\n ...\n rxe_qp_from_init {\n ...\n err1:\n ...\n qp->rcq = NULL; <---rcq is set to NULL\n qp->scq = NULL; <---scq is set to NULL\n ...\n }\n\nqp_init:\n rxe_put{\n ...\n rxe_qp_do_cleanup {\n ...\n atomic_dec(&qp->scq->num_wq); <--- scq is accessed\n ...\n atomic_dec(&qp->rcq->num_wq); <--- rcq is accessed\n }\n}"
