Descripcion

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Fix refcount leak when invalid session is found on session lookup When a session is found but its state is not SMB2_SESSION_VALID, It indicates that no valid session was found, but it is missing to decrement the reference count acquired by the session lookup, which results in a reference count leak. This patch fixes the issue by explicitly calling ksmbd_user_session_put to release the reference to the session.
