  "title": "RDMA/siw: Fix use-after-free in siw_accept()",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  RDMA/siw: Fix use-after-free in siw_accept()  siw_accept() looks up the QP supplied by userspace. If that QP is already in RTS, the function jumps to error cleanup before associating the incoming CEP with it.  The cleanup tests whether qp-\u003Ecep is non-NULL and assumes the current call installed the association. However, qp-\u003Ecep can point to the CEP of an existing connection. The cleanup then drops a reference from the incoming cep, not qp-\u003Ecep. Once the incoming endpoint loses its remaining references, this can free it before the subsequent cep-\u003Eqp store, causing a use-after-free. It also clears the existing QP association.  Only release the association reference when qp-\u003Ecep is the incoming CEP. This preserves an existing association and avoids accessing the freed endpoint.",
