Affects 0 products across 4 vendors.
Software writes data past buffer boundaries, corrupting memory and potentially enabling code execution.
VMware ESXi, Workstation, and Fusion contain an integer-underflow vulnerability in the VMCI that can lead to an out-of-bounds write, potentially allowing a local attacker with administrative privileges to execute arbitrary code on the host system. The impact is higher on Workstation and Fusion compared to ESXi due to the VMX sandboxing on ESXi.
BSID: BS-2025-GLOBAL-259598-C • Model: Qwen/Qwen2.5-72B-Instruct-AWQ • Confidence: HIGH

VMware ESXi, Workstation, and Fusion contain an integer-underflow in VMCI (Virtual Machine Communication Interface) that leads to an out-of-bounds write. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host. On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed.
Source: NIST NVD / MITRE CVE Database
The vulnerability exists in the VMCI component of VMware products. A local attacker with administrative privileges on a virtual machine can exploit the integer-underflow to perform an out-of-bounds write, leading to code execution on the host. This could result in full control over the host system, compromising the integrity and availability of the environment.

Implement strict access controls and least privilege principles for users and services interacting with the affected VMware products. Regularly monitor system logs for suspicious activity.
No reliable network detection signature exists for this vulnerability class — apply the compensating controls above and the vendor patch. A network rule is only drafted when a concrete on-the-wire signature can be grounded in the advisory.
This CVE violates CIP-007-R2 because it allows unauthorized access to the control center, which could compromise the security of the electronic security perimeter.
This CVE maps to SR 7.6 because it involves a vulnerability that can be exploited to gain unauthorized access to the system, which is a critical security concern in ICS environments.
Drafted by AI and not validated for your network. Test in an isolated environment before any production deployment. Compensating control only - does not replace vendor patch.
