VMware ESXi and Workstation TOCTOU Race Condition Vulnerability
Known Exploited Vulnerabilities CVE-2025-22224
VMware ESXi and Workstation contain a time-of-check time-of-use (TOCTOU) race condition vulnerability that leads to an out-of-bounds write. Successful exploitation enables an attacker with local administrative privileges on a virtual machine to execute code as the virtual machine's VMX process running on the host.
By exploiting the TOCTOU vulnerability in VMWare ESXi, Workstation, and Fusion, an attacker with local admin privileges can execute code in the VMX process on the host, in effect, functioning as an escape from the virtual machine to the host system.
