AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel. Users should update to patched kernel versions to remediate this issue. Since this is not a cloud service, manual patching is required. No additional mitigation steps are indicated.
Description
A critical vulnerability in the Linux kernel's NTFS implementation involves improper handling of zero-byte $DATA attributes. The function ntfs_resident_attr_resize() incorrectly attempts to convert zero-length resident $DATA attributes to non-resident, which leads to file system corruption as fsck treats these as corruptions.
