Critical Vulnerabilities Patched in VMware Workstation and Fusion Allowing Host Code Execution

Broadcom has disclosed two vulnerabilities in VMware Workstation and VMware Fusion rated as critical and important respectively. CVE-2026-59346 is an integer overflow flaw in the VMXNET3 virtual network adapter that can be exploited by a local administrator inside a virtual machine to execute arbitrary code on the host system, carrying a CVSS v3.1 base score of 9.3. CVE-2026-59347 is a stack-based buffer overflow in the HGFS file system that permits code execution on the host as the VMX process with a CVSS score of 8.1. Both issues were privately reported and affect users who run virtual machines with local administrative privileges. The flaws have been addressed in VMware Workstation 26H1u1 and VMware Fusion 26H1u1, and Broadcom urges immediate updates via advisory VMSA-2026-0007.

Advanced Windows Auditing Configuration Guide for Effective Incident Response in SOC Environments

The article provides a detailed walkthrough on configuring advanced audit policies in Windows 10 and Windows 11 to generate meaningful security events for incident investigation. It explains the role of the LSASS service in logging activities to the Security event log and contrasts basic auditing with the more granular advanced auditing that offers 53 subcategories. The guide covers enabling key subcategories such as Logon, Process Creation, and Account Management using auditpol commands, along with registry tweaks for PowerShell Script Block Logging and command-line auditing in process creation events. Practical tests demonstrate real-world events including successful and failed logons (Event IDs 4624 and 4625), process creation with arguments (Event ID 4688), and user account creation (Event IDs 4720 and 4732). All steps are performed on a VMware Workstation virtual machine running Windows 10 Pro 22H2 to avoid impacting production systems.
