In the Linux kernel, the following vulnerability has been resolved: ntfs: bound the free-cluster bitmap scan to the volume vol-lcn empty bits per page is sized from vol-nr clusters at mount, but ntfs cluster alloc bounds its scan of that array by the size of $Bitmap. Those are independent on-disk...
