Microsoft’s MDASH AI System Finds 16 Windows Flaws Fixed in Patch Tuesday

Microsoft has introduced a multi-model AI system called MDASH, designed to enhance vulnerability discovery and remediation processes. Currently in limited private preview testing with select customers, MDASH employs over 100 specialized AI agents for various classes of vulnerabilities, enabling autonomous discovery, validation, and demonstration of exploitable defects in complex codebases. The system operates through a structured pipeline that analyzes source code, constructs threat models, and validates findings using auditor and debater agents. MDASH has successfully identified 16 vulnerabilities in its initial tests, including two critical flaws affecting Windows networking and authentication: 1. CVE-2026-33824 (CVSS score: 9.8) - A double-free vulnerability in "ikeext.dll" allowing remote code execution via specially crafted packets. 2. CVE-2026-33827 (CVSS score: 8.1) - A race condition vulnerability in Windows TCP/IP ("tcpip.sys") enabling remote code execution through specially crafted IPv6 packets.

New GhostLock tool abuses Windows API to block file access

A security researcher has developed a proof-of-concept tool called GhostLock, which exploits a vulnerability in the Windows file API, specifically the 'CreateFileW' function. By manipulating the 'dwShareMode' parameter to grant exclusive access to files, GhostLock can prevent other users or applications from opening those files, resulting in a 'STATUSSHARINGVIOLATION' error. The tool automates the process of opening multiple files on SMB shares, causing access disruptions without requiring elevated privileges. This technique is intended as a disruption attack rather than a destructive one, similar to ransomware, and can serve as a diversion during intrusions. Detection of this attack relies on monitoring the open-file count with ShareAccess set to 0 at the file server layer. Dvash has provided resources for IT teams to enhance detection capabilities against this threat.

Microsoft Confirms KB5083769 Breaks Macrium and Acronis Backups

Microsoft's April 2026 Windows security update, KB5083769, may disrupt image-mount operations for backup applications such as Macrium Reflect, Acronis Cyber Protect Cloud, UrBackup Server, and NinjaOne Backup due to the addition of the psmounterex.sys kernel driver to its Vulnerable Driver Blocklist. This action was taken to address a high-severity buffer overflow vulnerability, CVE-2023-43896. The inclusion of this driver in the blocklist has rendered several backup products inoperable, and Microsoft will not retract the block for security reasons. Administrators can use Event ID 3077 in the Code Integrity log to confirm that the blocklist is causing the failures. Microsoft advises updating backup applications to versions that include necessary driver protections instead of uninstalling or pausing the security patch. Additionally, the April updates have caused other issues, such as failures in Windows Server installations and devices booting into BitLocker recovery mode.

Windows 11 restarts several times after a recent update? Don’t panic

After the installation of the optional April 2026 update, users may experience multiple restarts of their PCs, which is normal due to the Secure Boot certificate refresh process. This behavior may also occur with future updates as Microsoft implements Secure Boot certificate refreshes. Windows updates typically require a single reboot, but significant feature updates or firmware and driver updates may necessitate two or three reboots. Many Windows devices manufactured before 2024 have outdated Secure Boot certificates that need updating, as these certificates will expire in June 2026. Microsoft began rolling out updated Secure Boot certificates in March, but this rollout is staggered. Users can check their PC's Secure Boot certificate status in Windows Security under "Device security." The status is indicated by colored icons: green (up to date), yellow (update pending), and red (action required). Older devices may face issues with the certificate refresh if they lack up-to-date firmware or compatible BIOS updates. If Windows reports an error, the device manufacturer is typically responsible for resolving it. Users should verify that Secure Boot certificates were installed correctly after updates to ensure continued secure booting beyond June.

Microsoft’s latest Windows update now confirms if your PC is Secure Boot-protected

Microsoft has introduced a new feature in Windows 11 and Windows 10 that informs users about the status of Secure Boot as part of the April Patch Tuesday update. This feature includes a visual indicator that shows whether devices have the latest Secure Boot certificates, which protect against bootkit malware. The Secure Boot icon can display in green, yellow, or red, indicating different security statuses: green means secure with no actions needed, yellow indicates a pending safety recommendation, and red signals that immediate attention is required. Users can check their Secure Boot status through Settings in both operating systems. It is important to install the latest Windows updates to ensure devices have the most recent Secure Boot certificates, as older certificates will expire in June. The April updates also address 164 vulnerabilities, including eight classified as critical and two identified as zero-day flaws. Users are advised to prioritize these updates to maintain system security.
