Description OSIDB Bzimport 2025-02-26 03:19:10 UTC 
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.
