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's 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.
