That’s an interesting observation—because as of now, the SMBIOS specification is at version (depending on release dates), and the numeric versioning doesn’t go up to “26.”

• OS downgrade/upgrade cycles — check that SMBIOS fields remain stable across firmware updates where appropriate.
• Duplicated or missing UUIDs — ensure uniqueness or documented "not present" sentinel values.
