  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/siw: Clear association under lock if siw_qp_modify fails in siw_accept\n\nWe need to clear cep before release state_lock as siw_qp_llp_close and\nsiw_qp_modify->siw_qp_llp_close did.\n\nOtherwise if siw_qp_modify() fails in siw_accept(), the QP's state_lock\nis released before the error path cleanup. A concurrent ibv_modify_qp()\ntransitioning the QP to ERROR can race in this window:\n\n  siw_accept()                       ibv_modify_qp(ERROR)\n  ----------------------             ----------------------\n  siw_qp_modify() fails\n  up_write(&qp->state_lock)\n                                     down_write(&qp->state_lock)\n                                     nextstate_from_idle():\n\t\t\t\t     if (qp->cep)\n                                       siw_cep_put(qp->cep) <- frees cep\n                                       qp->cep = NULL\n  goto error\n    cep->qp = NULL                   <- UAF\n\nClear qp->cep and drop the association reference taken by siw_cep_get(),\nall under the write lock held from the initial down_write(&qp->state_lock).\nThread B therefore sees qp->cep == NULL, skips its own put, and cannot free\nthe cep before siw_accept() is done with it.",
