In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: provide block_invalidate_folio to fix memory leak The ntfs3 filesystem lacks the 'invalidate_folio' method and it causes memory leak. If you write to the filesystem and then unmount it, the cached written data are not freed and they are permanently leaked.
