VULNERABILITY DETAILS

Rockwell Automation used v3.1 and v4.0 of the CVSS scoring system to assess the following vulnerabilities.

CVE-2025-41236

An integer-overflow vulnerability exists in the VMXNET3 virtual network adapter used in VMware ESXi, Workstation, and Fusion. Exploitation of this vulnerability can lead to code execution on the host.

CVSS 3.1 Base Score: 9.3

CVSS Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

CVSS 4.0 Base Score: 9.4

CVSS Vector: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H

Known Exploited Vulnerability (KEV) database:  No

CVE-2025-41237

An integer-underflow vulnerability exists in the Virtual Machine Communication Interface (VMCI) of VMware ESXi, Workstation, and Fusion, which can lead to an out-of-bounds write. Exploitation of this vulnerability can lead to code execution on the host.

CVSS 3.1 Base Score: 9.3
