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.","state":0,"publishedAt":"2026-09-17T16:08:19.35+00:00","modifiedAt":"2026-10-19T09:01:10.469+00:00","affected":[{"ecosystem":"Vendor
