VMware, now part of Broadcom, has issued a critical security update on July 15, 2025, addressing several vulnerabilities in their ESXi server platform, Workstation, Fusion virtualization software for macOS, and VMware Tools. The identified flaws include integer overflow issues (CVE-2025-41236), VMCI Integer Underflow leading to Out-of-Bounds Write (CVE-2025-41237), PVSCSI Heap Overflow vulnerability (CVE-2025-41238), and a vSockets disclosure flaw (CVE-2025-41239). Each of these issues carries a CVSS base score ranging from 7.1 to 9.3, indicating that they are highly critical.
Users with local administrative privileges on virtual machines could potentially exploit these vulnerabilities to execute code on the host system or read sensitive information stored in vSockets processes. VMware ESXi, Workstation Pro for Windows and macOS, Fusion, and the latest VMware Tools versions are affected. The updates provided by VMware can mitigate these risks, but users will need a Broadcom Support Portal account to access them.
As an IT security professional, I cannot stress enough how crucial it is to promptly apply these patches once they become available to your organization’s infrastructure. Delaying these updates could expose your systems to significant vulnerabilities that malicious actors might exploit. Additionally, organizations should consider conducting regular penetration testing and maintaining robust intrusion detection systems to further safeguard against potential threats.
For more detailed information on the security advisories published by VMware, including specific instructions for applying the patches, users are encouraged to visit the official Broadcom Support website or consult reputable third-party resources like deskmodder.de. These platforms often provide additional insights into the nature of vulnerabilities and practical advice on implementing security measures effectively.
