      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: fix smbd_connection leak on cifs_get_tcp_session() error\n\nWhen an RDMA connection is successfully established via\nsmbd_get_connection() but cifs_get_tcp_session() later fails (e.g.\nkthread_create() returns an error), the error path frees tcp_ses\nwithout first destroying the smbd_connection.\n\nFix this by calling smbd_destroy() in the out_err cleanup path before\nkfree(tcp_ses).  smbd_destroy() safely handles the case where\nsmbd_conn is NULL, so it can be called unconditionally.",
