Summary

In the Linux kernel, the following vulnerability has been resolved: ntfs: validate resident index root values on lookup Resident $INDEX_ROOT values carry index header fields that callers consume after lookup. Some callers already validate parts of the layout before walking entries, but those checks are scattered and do not cover all root header invariants, such as entries_offset alignment and lower bound, index_length, and allocated_size consistency. The resident root resize paths now keep t…
