Details

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.

Severity

5.5 (Medium)
