* kernel: stack-based out-of-bounds write in ntfs_end_buffer_async_read in the ntfs.ko (CVE-2018-12930)

* kernel: stack-based out-of-bounds write in ntfs_attr_find in the ntfs.ko (CVE-2018-12931)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
