Patchday Microsoft: Angreifer nutzen Windows- und Word-Lücken aus 11.02.2026

Microsoft hat wichtige Sicherheitsupdates für verschiedene Produkte veröffentlicht, darunter Exchange Server, Hyper-V, Office und Windows, da Angreifer derzeit sechs Sicherheitslücken ausnutzen. Diese Schwachstellen, die Internet Explorer, Windows und Word betreffen, können im schlimmsten Fall zur Ausführung von Schadcode und zur vollständigen Übernahme von Systemen führen. Eine der ausgenutzten Lücken (CVE-2026-21510) umgeht den SmartScreen-Schutzmechanismus von Windows, während eine andere (CVE-2026-21514) die Ausführung von Schadcode nach dem Öffnen eines manipulierten Word-Dokuments ermöglicht. Die US-Cybersicherheitsbehörde CISA hat alle sechs ausgenutzten Lücken in ihren Katalog bekannter ausgenutzter Schwachstellen aufgenommen.
