Description
CVE-2025-41237 is a critical out-of-bounds write vulnerability in VMware ESXi, Workstation, and Fusion products caused by an integer underflow in the VMCI component. A local attacker with administrative privileges inside a virtual machine can exploit this flaw to execute code as the VMX process on the host. On ESXi, exploitation is limited to the VMX sandbox, while on Workstation and Fusion, it may lead to code execution on the host machine. The vulnerability affects multiple versions including 9.0.0.0, 5.x, and 4.5.x.
