CVE-2026-31609

EUVD-2026-25502
In the Linux kernel, the following vulnerability has been resolved:

smb: client: avoid double-free in smbd_free_send_io() after smbd_send_batch_flush()

smbd_send_batch_flush() already calls smbd_free_send_io(),
so we should not call it again after smbd_post_send()
moved it to the batch list.
