CVE-2026-31608

EUVD-2026-25501
In the Linux kernel, the following vulnerability has been resolved:

smb: server: avoid double-free in smb_direct_free_sendmsg after smb_direct_flush_send_list()

smb_direct_flush_send_list() already calls smb_direct_free_sendmsg(),
so we should not call it again after post_sendmsg()
moved it to the batch list.
