• CVE-2025-22224 (CVSS 9.3): A Time-of-Check Time-of-Use (TOCTOU) vulnerability in VMware ESXi and Workstation that can lead to an out-of-bounds write condition. An attacker with local administrative privileges on a virtual machine could exploit this issue to execute code as the virtual machine's VMX process running on the host.
  
• CVE-2025-22225 (CVSS 8.2): An arbitrary write vulnerability in VMware ESXi that allows an attacker with privileges within the VMX process to trigger an arbitrary kernel write leading to an escape of the sandbox.
  
• CVE-2025-22226 (CVSS 7.1): An information disclosure vulnerability in VMware ESXi, Workstation, and Fusion that arises from an out-of-bounds read in the Host Guest File System (HGFS). An attacker with administrative privileges to a virtual machine could exploit this issue to leak memory from the VMX process.
  

I don't directly deal with our ESXi systems at work, but they were up patching systems tonight for this. A few days late  but...NMFP!
