CVE-2026-72199: In the Linux kernel, the following vulnerability has been resolved: ntfs: validate resident index root values
CVE-2026-72199 is a critical-severity flaw (CVSS 9.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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 consis
