  "title": "ksmbd: scope session state changes to bound connections",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  ksmbd: scope session state changes to bound connections  ksmbd_all_conn_set_status() treats every connection whose transient binding flag is set as belonging to the target SessionId.  A logoff or session replacement can consequently move an unrelated connection to NEED_RECONNECT or NEED_SETUP.  Pass the target session itself and select connections using either the connection-local session xarray or the session\u0027s permanent channel list. Use the same association test while waiting for requests to drain.  Serialize session-wide status changes under request_lock and do not overwrite EXITING or RELEASING. Protect the shutdown transition with the same lock so a concurrent session update cannot revive a closing connection.",
