CVE-2025-38357 (published 2025-07-25 13:15:24.463000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

fuse: fix runtime warning on truncate_folio_batch_exceptionals()

The WARN_ON_ONCE is introduced on truncate_folio_batch_exceptionals() to
capture whether the filesystem has removed all DAX entries or not.

And the fix has been applied on the filesystem xfs and ext4 by the commit
0e2f80afcfa6 ("fs/dax: ensure all pages are idle prior to filesystem
unmount").

Apply the missed fix on filesystem fuse to fix the runtime warning:
