  "summary": "RDMA/siw: Fix use-after-free in siw_accept()",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/siw: Fix use-after-free in siw_accept()\n\nsiw_accept() looks up the QP supplied by userspace. If that QP is\nalready in RTS, the function jumps to error cleanup before associating\nthe incoming CEP with it.\n\nThe cleanup tests whether qp->cep is non-NULL and assumes the current\ncall installed the association. However, qp->cep can point to the CEP\nof an existing connection. The cleanup then drops a reference from the\nincoming cep, not qp->cep. Once the incoming endpoint loses its\nremaining references, this can free it before the subsequent cep->qp\nstore, causing a use-after-free. It also clears the existing QP\nassociation.\n\nOnly release the association reference when qp->cep is the incoming\nCEP. This preserves an existing association and avoids accessing the\nfreed endpoint.",
