Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot de volgende categorie\u00ebn schade:\n\n- Denial-of-Service (DoS)\n- Uitvoeren van willekeurige code (root/admin-rechten)\n- Uitvoeren van willekeurige code (gebruikersrechten)\n- Verkrijgen van verhoogde rechten\n- Omzeilen van een beveiligingsmaatregel\n- Toegang tot gevoelige gegevens\n\nDe ernstigste kwetsbaarheden hebben kenmerken CVE-2026-40402, CVE-2026-41089 en CVE-2026-41096 toegewezen gekregen en bevinden zich respectievelijk in Hyper-V, NETLOGON en de DNS Client. De kwetsbaarheid in Hyper-V stelt een geauthenticeerde kwaadwillende in staat om uit de Guest-VM te breken en toegang te krijgen tot geheugen van de host en mogelijk willekeurige code uit te voeren op de host. De kwetsbaarheden in NETLOGON en de DNS Client stellen een ongeauthenticeerde kwaadwillende op afstand in staat om willekeurige code uit te voeren op het kwetsbare systeem.\n\n**Met name Domain Controllers die toegankelijk zijn vanaf externe netwerken lopen een hoog risico voor actief misbruik van de kwetsbaarheid in NETLOGON.**\n\nHet verdient altijd aanbeveling om een systeem met de rol van Domain Controller niet publiek toegankelijk te hebben en, indien dit noodzakelijk is, additionele maatregelen te hebben genomen.\n\n**Update:** Inmiddels wordt door diverse partijen actief misbruik gemeld van CVE-2026-41089, de kwetsbaarheid in NETLOGON.\n\n```\nWindows Projected File System: \n|----------------|------|-------------------------------------|\n| CVE-ID | CVSS | Impact

Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot de volgende categorie\u00ebn schade:\n\n- Denial-of-Service (DoS)\n- Uitvoeren van willekeurige code (root/admin-rechten)\n- Uitvoeren van willekeurige code (gebruikersrechten)\n- Verkrijgen van verhoogde rechten\n- Omzeilen van een beveiligingsmaatregel\n- Toegang tot gevoelige gegevens\n\nDe ernstigste kwetsbaarheden hebben kenmerken CVE-2026-40402, CVE-2026-41089 en CVE-2026-41096 toegewezen gekregen en bevinden zich respectievelijk in Hyper-V, NETLOGON en de DNS Client. De kwetsbaarheid in Hyper-V stelt een geauthenticeerde kwaadwillende in staat om uit de Guest-VM te breken en toegang te krijgen tot geheugen van de host en mogelijk willekeurige code uit te voeren op de host. De kwetsbaarheden in NETLOGON en de DNS Client stellen een ongeauthenticeerde kwaadwillende op afstand in staat om willekeurige code uit te voeren op het kwetsbare systeem.\n\n**Met name Domain Controllers die toegankelijk zijn vanaf externe netwerken lopen een hoog risico voor actief misbruik van de kwetsbaarheid in NETLOGON.**\n\nHet verdient altijd aanbeveling om een systeem met de rol van Domain Controller niet publiek toegankelijk te hebben en, indien dit noodzakelijk is, additionele maatregelen te hebben genomen.\n\n**Update:** Inmiddels wordt door diverse partijen actief misbruik gemeld van CVE-2026-41089, de kwetsbaarheid in NETLOGON.\n\n```\nWindows Projected File System: \n|----------------|------|-------------------------------------|\n| CVE-ID | CVSS | Impact
