CVE-2026-64383

In the Linux kernel, the following vulnerability has been resolved:

smb: client: fix double-free in SMB2_flush() replay

SMB2_flush() keeps its response buffer bookkeeping across replay

attempts. If a replayable flush response is received and the retry then

fails before cifs_send_recv() stores a replacement response, flush_exit

will free the stale response pointer a second time.

Reinitialize resp_buftype and rsp_iov at the top of the replay loop so

cleanup only acts on response state produced by the current attempt.

This fixes a double-free without changing replay handling for successful

requests.
