Summary

In the Linux kernel, the following vulnerability has been resolved:

ntfs: not change 0-byte $DATA attribute to non-resident

When ntfs_resident_attr_resize() cannot grow a resident attribute in place, it retries after converting other resident attributes to non-resident to free space in the MFT recrord.

Do not select zero-length resident $DATA attributes for this conversion. fsck treats 0-byte non-resident $DATA attribute as corruptions.
