Summary
Microsoft heeft kwetsbaarheden verholpen in Windows
Details
Interpretaties
Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot de volgende categoriën schade:
- Denial-of-Service (DoS)
- Manipulatie van gegevens
- Toegang tot gevoelige gegevens
- Uitvoeren van willekeurige code (gebruikersrechten)
- Uitvoeren van willekeurige code (root/admin)
- Verkrijgen van verhoogde rechten
- Omzeilen van een beveiligingsmaatregel
- Spoofing
Van de kwetsbaarheid met kenmerk CVE-2026-21265 meldt Microsoft informatie te hebben dat deze publiekelijk besproken wordt op fora. Een kwaadwillende kan de kwetsbaarheid misbruiken om Secure Boot te omzeilen. Misbruik is echter niet eenvoudig, vereist voorafgaande verhoogde rechten en een diepgaande kennis van het te compromitteren systeem. Grootschalig misbruik is hiermee zeer onwaarschijnlijk.
Van de kwetsbaarheid met kenmerk CVE-2026-20805 meldt Microsoft dat deze als zeroday-kwetsbaarheid is misbruikt. Misbruik vereist lokale toegang en voorafgaande gebruikersauthenticatie. Verdere informatie is niet bekend gesteld. Grootschalig misbruik is niet waarschijnlijk.
De kwetsbaarheid met kenmerk CVE-2023-31096 is een oudere kwetsbaarheid in Broadcom modem drivers, zoals gebruikt in de (verouderde) Agere modems. Hiervan is al langer Proof-of-Concept-code bekend, maar grootschalig misbruik heeft voor zover bekend nog niet plaatsgevonden. Microsoft heeft in deze update de drivers verwijderd.
Een kwaadwillende kan deze kwetsbaarheid met kenmerk CVE-2026-20817 misbruiken doordat Windows Error Reporting onvoldoende controle uitvoert op rechten en privileges, waardoor een geautoriseerde aanvaller lokaal zijn rechten kan verhogen. Voor deze kwetsbaarheid is Proof-of-Concept-Code (PoC) verschenen. Het NCSC verwacht een toename in scan- en misbruikverkeer, waardoor de kans op misbruik kan toenemen.
