That's not all. September's Patch Tuesday also fixed two zero-days under active exploitation: CVE - 2026 -85880, a heap buffer overflow in Windows ALPC that allows local privilege escalation to SYSTEM, and CVE - 2026 -81963, a link-following flaw in the Windows Update Stack. Rolling back removes those fixes too.
