- This OS heading is inconsistent with the other Windows 10 rows (which use the "Windows 10, version <...>" format). Using the same format improves scanability and avoids ambiguity about what "1809" refers to.
This issue also appears on line 62 of the same file.

- The link text includes a trailing period inside the brackets ("[CVE-2026-69522.]") and the sentence then lacks terminal punctuation. Move the period outside the link so the CVE identifier is correct and the sentence ends cleanly.

- This OS heading is inconsistent with the other Windows 10 rows (which use the "Windows 10, version <...>" format). Use the same naming pattern here for consistency.
