Will the Microsoft Defender 'RoguePlanet' zero-day be actively exploited before a patch is released?

Bleeping Computer reports a zero-day vulnerability in Microsoft Defender branded 'RoguePlanet' that grants SYSTEM privileges. This is a critical local privilege escalation in one of the world's most widely deployed security products. Verification will rely on public CVE disclosure, Microsoft security advisories, and evidence of real-world exploitation.

Resolution Criteria

YES if CVE is disclosed, assigned a CVSS score of 7.0 or higher, and public evidence (e.g., CISA KEV, vendor advisory, security researcher reports) confirms active exploitation before Microsoft patches. NO if patched without documented wild exploitation.
