  "title": "RDMA/siw: Clear association under lock if siw_qp_modify fails in siw_accept",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  RDMA/siw: Clear association under lock if siw_qp_modify fails in siw_accept  We need to clear cep before release state_lock as siw_qp_llp_close and siw_qp_modify-\u003Esiw_qp_llp_close did.  Otherwise if siw_qp_modify() fails in siw_accept(), the QP\u0027s state_lock is released before the error path cleanup. A concurrent ibv_modify_qp() transitioning the QP to ERROR can race in this window:    siw_accept()                       ibv_modify_qp(ERROR)   ----------------------             ----------------------   siw_qp_modify() fails   up_write(\u0026qp-\u003Estate_lock)                                      down_write(\u0026qp-\u003Estate_lock)                                      nextstate_from_idle(): \t\t\t\t     if (qp-\u003Ecep)                                        siw_cep_put(qp-\u003Ecep) \u003C- frees cep                                        qp-\u003Ecep = NULL   goto error     cep-\u003Eqp = NULL                   \u003C- UAF  Clear qp-\u003Ecep and drop the association reference taken by siw_cep_get(), all under the write lock held from the initial down_write(\u0026qp-\u003Estate_lock). Thread B therefore sees qp-\u003Ecep == NULL, skips its own put, and cannot free the cep before siw_accept() is done with it.",
