The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix BUG: KASAN: null-ptr-     deref in rxe_qp_do_cleanup The function rxe_create_qp calls rxe_qp_from_init. If some error occurs, the     error handler of function rxe_qp_from_init will set both scq and rcq to NULL. Then rxe_create_qp calls     rxe_put to handle qp. In the end, rxe_qp_do_cleanup is called by rxe_put. rxe_qp_do_cleanup directly     accesses scq and rcq before checking them. This will cause null-ptr-deref error. The call graph is as     below: rxe_create_qp { ... rxe_qp_from_init { ... err1: ... qp->rcq = NULL; <---rcq is set to NULL qp->scq     = NULL; <---scq is set to NULL ... } qp_init: rxe_put{ ... rxe_qp_do_cleanup { ...
    atomic_dec(&qp->scq->num_wq); <--- scq is accessed ... atomic_dec(&qp->rcq->num_wq); <--- rcq is accessed     } } (CVE-2022-50135)

Note that Nessus relies on the presence of the package as reported by the vendor.
