The existing checks on fp->refcount are not sufficient to\nprevent this.\n\nThe fix takes ft->lock around the section which removes the\nfile from the file table.

Es posible un use-after-free si un hilo destruye el archivo mediante __ksmbd_close_fd mientras otro hilo mantiene una referencia a él. Las comprobaciones existentes en fp->refcount no son suficientes para evitarlo. La corrección aplica ft->lock a la sección que elimina el archivo de la tabla de archivos.
