cve 2026 65784

CVE-2026-65784 is a Windows NTFS information-disclosure vulnerability that Microsoft published on August 11, 2026. The primary action for administrators is to deploy the August 2026 Windows security updates to all supported Windows client and server editions listed in Microsoft's Security Update Guide, then verify the cumulative update installed correctly. Microsoft's advisory identifies the affected component and impact class but does not publicly disclose the root cause, the data at risk, the required attacker access, or the attack path. This makes CVE-2026-65784 a patching priority rather than a vulnerability that can be mitigated through configuration changes, emphasizing the importance of timely update deployment.
