The visible Rapid7 list includes several 9.8 remote code execution bugs; each entry is marked not publicly disclosed.

Rapid7's November 2026 Patch Tuesday post lists Microsoft fixes across Active Directory, Desktop Window Manager, graphics, media extensions, HID, HTTP.sys, PowerShell, and other Windows components. Entries include remote code execution, elevation of privilege, information disclosure, and denial of service, with CVSS scores up to 9.8. Exploitation is rated unlikely, less likely, or more likely; the excerpt does not say any flaw is being attacked. The list is cut off at Microsoft Raw Image Extension.

Unconfirmed: The excerpt is truncated, so the full set of November fixes is not shown.

Key facts
  • Microsoft Color Management and DirectMusic include remote code execution flaws scored 9.8.
  • One Desktop Window Manager elevation-of-privilege bug is rated exploitation more likely.
  • Two AMD Zen information-disclosure issues are scored 5.5.
