      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: scope conn->binding slowpath to bound sessions only\n\nWhen the binding SESSION_SETUP sets conn->binding = true, the flag stays\nset after the call so that the global session lookup in\nksmbd_session_lookup_all() can find the session, which was not added to\nconn->sessions. Because the flag is connection-wide, the global lookup\npath will also resolve any other session by id if asked.\n\nTighten the global lookup so that the returned session must have this\nconnection registered in its channel xarray (sess->ksmbd_chann_list).\nThe channel entry is installed by the existing binding_session path in\nntlm_authenticate()/krb5_authenticate() when a SESSION_SETUP completes\nsuccessfully, so this condition is a strict equivalent of \"this\nconnection has been accepted as a channel of this session\". Connections\nthat have not bound to a given session cannot reach it via the global\ntable.\n\nThe existing conn->binding gate for entering the slowpath is preserved\nso that non-binding connections keep the fast-path-only behavior, and\nthe session->state check is unchanged.",
