Another good catch by @TomSellers - VMware's website advisory has less detail than their github for some reason.
Their github: https://github.com/vmware/vcf-security-and-compliance-guidelines/tree/main/security-advisories/vmsa-2025-0004
According to their Github, additional VMware ESXi versions are impacted (e.g. 6.5, 6.7) and older versions are likely impacted but no patches available.
An in the wild exploit for RCE hypervisor escape across every supported (and unsupported) product like this is unprecedent.
